Prep the chicken and veggies: Pat the chicken dry and slice it evenly so it cooks quickly. Slice onions and peppers thin to soften fast without getting soggy.
Warm the pan: Heat the olive oil in a large skillet over medium-high heat.
You want a lively sizzle when the chicken hits the pan.
Season and sear: Toss chicken with salt, pepper, cumin, chili powder, and smoked paprika. Add to the hot skillet in a single layer. Sear 2–3 minutes per side until lightly browned.
Don’t fully cook through yet. Transfer to a plate.
Soften the vegetables: In the same skillet, add onion and peppers with a pinch of salt. Cook 4–5 minutes, stirring occasionally, until softened and lightly charred in spots.
Add garlic and deglaze: Stir in the garlic for 30 seconds until fragrant.
Pour in the chicken broth, scraping up brown bits from the pan for extra flavor.
Build the sauce: Stir in the fire-roasted salsa. Bring to a gentle simmer.
Finish the chicken: Return the chicken and any juices to the skillet. Stir and simmer 3–5 minutes, until the chicken is cooked through and the sauce slightly thickens.
Brighten it up: Squeeze in lime juice and stir in chopped cilantro.
Taste and adjust salt or lime as needed.
Serve your way: Spoon over cauliflower rice for a lower-calorie base, or serve with a side salad. Add avocado, jalapeño, or a dollop of Greek yogurt if you like.
