Prep the base: Cook rice, quinoa, or cauliflower rice according to package directions.
Fluff and set aside. If using greens, wash and chop them.
Season the chicken: Pat the chicken dry. Toss with garlic powder, onion powder, salt, and pepper.
Cook the chicken: Heat oil in a large skillet over medium-high.
Add chicken in a single layer. Sear 4–6 minutes, stirring occasionally, until cooked through and lightly browned.
Buffalo it up: Lower heat to medium. Stir in Buffalo sauce and melted butter, if using.
Simmer 1–2 minutes to coat the chicken and slightly thicken the sauce.
Prep toppings: While the chicken cooks, chop celery, cucumber, tomatoes, carrots, avocado, and green onions. Crumble cheese and rough-chop herbs.
Assemble the bowls: Add a scoop of your base to each bowl. Top with greens.
Spoon on the Buffalo chicken and any extra sauce from the pan.
Finish with crunch and cream: Add celery, cucumber, tomatoes, carrots, avocado, and cheese. Drizzle with ranch or blue cheese dressing. Sprinkle with green onions and herbs.
Brighten it up: Squeeze fresh lemon or lime over the top to balance the heat.
Taste and adjust salt or dressing.
