Marinate the chicken. In a bowl, combine half the BBQ sauce with 1 tablespoon olive oil, 1 teaspoon chili powder, 1/2 teaspoon garlic powder, 1/2 teaspoon smoked paprika, a pinch of salt, and pepper.
Add the chicken and coat well. Let it sit for 15–30 minutes (or up to overnight in the fridge for deeper flavor).
Cook the grains. Prepare brown rice or quinoa according to package directions. Fluff and set aside.
For a low-carb option, sauté cauliflower rice in a little olive oil with salt and pepper until tender.
Prep the veggies. Halve tomatoes, dice bell pepper, slice red onion, chop romaine, and rinse the black beans. If using fresh corn, cut kernels from the cob. If frozen or canned, drain well so the bowls don’t get watery.
Cook the corn (optional but tasty). Heat a skillet over medium-high with a teaspoon of oil.
Add corn and cook 3–5 minutes until lightly charred. Season with salt and a squeeze of lime.
Grill or pan-cook the chicken. Grill over medium-high heat for 5–7 minutes per side, or cook in a hot skillet with a drizzle of oil for 6–8 minutes per side, until the internal temperature reaches 165°F (74°C). Brush with the remaining BBQ sauce in the last minute for a glossy finish.
Rest 5 minutes, then slice.
Make the ranch drizzle. If your ranch is thick, whisk with a splash of water or lime juice to make it spoonable. For extra zing, mix in a pinch of smoked paprika and a squeeze of lime.
Assemble the bowls. Add a bed of grains and greens. Top with sliced chicken, corn, black beans, tomatoes, bell pepper, and red onion.
Add avocado just before serving. Drizzle with ranch and a light extra swirl of BBQ if you like.
Finish with fresh elements. Sprinkle cilantro, add lime wedges, and any extras like shredded cheese, pickled jalapeños, or crushed tortilla chips for crunch.
Taste and adjust. Add a pinch of salt, a squeeze more lime, or another spoon of ranch if needed. You want every bite balanced and bright.
