Cook your base: Make rice, quinoa, or cauliflower rice according to package directions. Fluff with a fork and keep warm.
Squeeze in a little lime juice and sprinkle with chopped cilantro for extra flavor.
Mix the fajita seasoning: In a small bowl, combine chili powder, cumin, smoked paprika, oregano, onion powder, garlic powder (if using), cayenne, salt, and pepper.
Season the chicken: Pat the chicken dry. Toss with half the seasoning, 1 tablespoon oil, and minced garlic (if using fresh). Let it sit while you prep the veggies.
Slice the veggies: Cut bell peppers and onion into thin strips.
Toss with the remaining seasoning and 1 tablespoon oil.
Sear the chicken: Heat a large skillet over medium-high until hot. Add a little oil. Cook chicken in a single layer, undisturbed for 2–3 minutes, then stir and cook until just cooked through and lightly charred at the edges, about 5–7 minutes total.
Transfer to a plate and squeeze with lime.
Sauté peppers and onions: In the same skillet, add another drizzle of oil if needed. Cook peppers and onions over medium-high heat, stirring occasionally, until softened and slightly charred in spots, about 5–7 minutes. Season with a pinch of salt and a squeeze of lime.
Warm optional add‑ins: If using black beans or corn, toss them into the hot pan for 1–2 minutes to warm through.
This adds flavor and keeps everything hot.
Assemble the bowls: Divide rice among bowls. Top with chicken, peppers, and onions. Add your favorite toppings: avocado, salsa, cheese, sour cream or Greek yogurt, cilantro, and extra lime.
Finish and serve: Taste and adjust with more lime or salt.
Serve immediately while it’s hot and the toppings are cool and fresh.
