Preheat the grill or grill pan to medium-high heat.
Season the chicken breasts with olive oil, salt, pepper, garlic powder, and paprika.
Grill the chicken for 6-7 minutes per side or until fully cooked (internal temperature should reach 165°F).
While the chicken is grilling, prepare the guacamole by mashing the avocado and mixing it with lime juice, chopped cilantro, and hot sauce (if using). Set aside.
Assemble the bowl by placing a base of cooked quinoa in the center of each bowl.
Top with a handful of mixed greens, cherry tomatoes, cucumber, red onion, corn, and black beans.
Slice the grilled chicken and arrange it on top of the veggies.
Add a generous scoop of guacamole to each bowl and garnish with extra cilantro if desired.
Serve immediately and enjoy!
