Start with marinating the chicken. Add all marinade ingredients to a mason jar and give it a good shake. Place chicken and pour marinade into a large zip-lock bag. Set aside for at least 30 mins.
Next, prepare the veggies for the grill. Slice 2 bell peppers and 1 whole onion. Toss them in 1/4 cup oil and seasonings. Use grill basket or aluminum foil pouch for the grill (or simply saute the veggies on the stove!)
Drain, rinse, and heat beans in a small saucepan. Add a little salt, pepper, paprika, cumin, and a splash of water to spice things up.
Assemble bowls! Start with rice, add chopped chicken, grilled veggies, beans, and avocado and/or salsa on top! (Cauliflower rice would be a great low carb/whole 30 substitute in this recipe.)
