Cook the chicken: Bake or grill the chicken breast at 400°F (200°C) for about 20 minutes or until fully cooked. Let it rest before slicing.
Mix the cottage cheese base: In a bowl, combine the cottage cheese and ranch dressing until smooth and creamy.
Coat the chicken: Toss the sliced chicken in BBQ sauce until evenly coated.
Assemble the bowl: Layer the cottage cheese mixture at the bottom of a serving bowl. Add the BBQ chicken on top and sprinkle with shredded cheddar cheese.
Serve and enjoy: Drizzle with extra BBQ sauce if desired and serve warm.
