Mexican Pork Tenderloins — Roberto’s Recipe, the First Meal of the After

I got vaccinated. January 15th, a Friday, at the convention center on 7th Street. I sat in the observation area with a Band-Aid on my left arm and my phone in my hand and I texted Jessica a photo — just the bandage, just the arm, no caption needed. She responded with seventeen heart emojis. I counted them. Seventeen. One for each month since the pandemic started.

The shot itself was nothing — a pinch, a brief soreness, the same as a flu shot. The significance was everything. I sat in that observation chair for the required fifteen minutes and I thought about March 2020. About the decontamination station in the garage. About Sofia asking, "Daddy, why can you not hug me?" About Diego reaching for me while I walked past him to the shower. About Roberto behind the screen door. About the cold grill. About the ninety-two porch drops. About the woman who died because she was afraid to go to the doctor. About all of it.

The vaccine does not erase any of that. It does not bring back the months we lost. It does not restore the cookouts or the hugs or the Sunday mornings at Roberto's grill. But it is the first step toward all of that coming back, and the first step is the one that matters most, because it proves that the next step is possible.

I called Roberto from the parking lot. I said, "I got it, Dad. The first shot." He was quiet. Then he said, "Good. Now come get me an appointment." Roberto Rivera, sixty-three years old, diabetic, terrified of needles (a fact he has never admitted and that Elena confirms annually), is asking for the vaccine. Not because he wants the needle. Because he wants the grill. Because he wants the Sunday cookout. Because he wants to stand next to his son at the fire and not be afraid.

I registered Roberto and Elena that night. Their appointments are in February — Phase 1B, high-risk adults over sixty. Six weeks from now, my parents will be vaccinated. Two months from now, the Rivera Sunday cookout can return. The timeline is real. The math works. The fire is coming back.

That night I cooked. Not for delivery, not for the hospital, not for the firehouse. For us. For my family. Carne asada, Roberto's recipe, on my grill, at sunset. Jessica and Sofia and Diego at the table. The Band-Aid still on my arm. The first meal of the after.

Roberto’s carne asada has always been the anchor of the Rivera Sunday cookout — the smell of it, the fire under it, the way everyone drifts toward the grill without being called. That night, with the Band-Aid still on my arm and my parents’ vaccine appointments finally on the calendar, I needed to cook something that tasted like what was coming back. These Mexican Pork Tenderloins carry all of that — the citrus marinade, the char, the cumin — the flavors Dad has been building on that grill for thirty years. It wasn’t the full Sunday cookout yet, but it was the first real fire we’d had in a long time, and that was enough.

Mexican Pork Tenderloins

Prep Time: 15 min | Cook Time: 25 min | Total Time: 40 min (plus 2 hrs marinating) | Servings: 6

Ingredients

  • 2 pork tenderloins (about 1 lb each), trimmed
  • 1/4 cup fresh lime juice (about 3 limes)
  • 3 tablespoons olive oil
  • 4 cloves garlic, minced
  • 2 teaspoons ground cumin
  • 2 teaspoons chili powder
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried oregano
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon cayenne pepper
  • 2 tablespoons fresh cilantro, chopped, for serving
  • Lime wedges, for serving

Instructions

  1. Make the marinade. In a small bowl, whisk together the lime juice, olive oil, garlic, cumin, chili powder, smoked paprika, oregano, salt, black pepper, and cayenne until combined.
  2. Marinate the pork. Place the tenderloins in a zip-top bag or shallow dish. Pour the marinade over the pork, turning to coat evenly. Seal and refrigerate for at least 2 hours, or up to overnight for deeper flavor.
  3. Preheat the grill. Heat an outdoor grill or grill pan to medium-high heat (about 400°F). Oil the grates lightly to prevent sticking.
  4. Grill the tenderloins. Remove the pork from the marinade and let any excess drip off. Grill for 20–25 minutes, turning every 5–6 minutes, until all sides are nicely charred and an instant-read thermometer inserted into the thickest part reads 145°F.
  5. Rest the meat. Transfer the tenderloins to a cutting board and tent loosely with foil. Let rest for 5 minutes — this keeps the juices locked in.
  6. Slice and serve. Cut crosswise into 1/2-inch medallions. Arrange on a platter, scatter fresh cilantro over the top, and serve with lime wedges alongside.

He's won a couple of local BBQ competitions, built an outdoor kitchen his wife calls "the altar," and feeds his fire crew on every shift. For Marcus, cooking isn't a hobby — it's how he shows up for the people he loves.
