Heat olive oil in a large skillet over medium-high heat.
Add the ground turkey to the skillet and cook, breaking it into crumbles, until browned and no longer pink (internal temperature 165°F).
Sprinkle the taco seasoning over the meat and add 1/4 cup water; stir to combine and simmer for 3-5 minutes until the sauce has thickened.
In a separate small pan or microwave-safe bowl, warm the black beans and corn until heated through.
Divide the cooked brown rice equally among four serving bowls.
Layer the seasoned turkey, black beans, and corn over the rice.
Top each bowl with cherry tomatoes, avocado slices, and shredded cheese.
Garnish with fresh cilantro and serve with lime wedges.
