On the other side of the sheet pan, add the 1 lb tomatillos, 1 small white onion, 1 jalapeño, and 3 cloves garlic. Drizzle with 1 tbsp olive oil, sprinkle with ½ tsp kosher salt, and toss to coat. Spread everything out so it roasts evenly.

Roast for 25–30 minutes, flipping the chicken halfway through, until the chicken is cooked through (internal temp of 165°F) and the tomatillos are blistered, soft, and lightly charred.
Transfer the roasted tomatillos, onion, jalapeños, and garlic to a blender or food processor. Add the juiced 1 lime and 1 tsp lime zest. Blend until smooth or slightly chunky, depending on preference. Taste and adjust seasoning with salt or a squeeze of lime if desired.

Let the chicken rest for 5 minutes, then slice or shred. Toss with a few spoonfuls of the roasted salsa verde for extra flavor.
Fill warm Corn tortillas with the Spanish rice and chicken, drizzle with more salsa verde, and finish with Fresh cilantro leaves, Lime wedges, and Crumbled cotija cheese.
