Preheat the oven: Set to 400°F (200°C). Lightly oil a 9x13-inch baking dish.
Mix the spice rub: In a small bowl, combine cumin, chili powder, garlic powder, onion powder, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
Season the chicken: Pat chicken breasts dry.
Rub with olive oil, then coat both sides with the spice mix.
Layer the dish: Pour 1 cup salsa verde into the baking dish and spread it out. Nestle the chicken on top.
Add brightness: Zest the lime over the chicken. Squeeze half the lime’s juice over everything.
Sprinkle with half the cilantro.
Top with sauce: Pour the remaining 1 cup salsa verde over the chicken. If you like it saucier, splash in the broth or water around the sides.
Bake: Cover with foil and bake for 15 minutes.
Add cheese: Remove the foil, sprinkle cheese over the chicken, and bake uncovered for another 8–12 minutes, until the chicken reaches 165°F (74°C) in the thickest part.
Rest and finish: Let rest 5 minutes. Squeeze the remaining lime juice over the top and scatter on the rest of the cilantro.
Serve: Spoon the saucy chicken over brown rice or cauliflower rice.
Add avocado and extra lime if you like.
