Finely dice the red onion, bell pepper, and zucchini into uniform pieces.
Heat the extra virgin olive oil in a large non-stick skillet over medium-high heat.
Add the ground turkey to the skillet, breaking it apart with a spatula, and cook until browned and no longer pink.
Stir in the diced onion, bell pepper, and zucchini, cooking for 4-5 minutes until the vegetables are tender-crisp.
Add the ground cumin, chili powder, garlic powder, sea salt, and black pepper to the mixture, stirring well to coat the turkey and vegetables.
Fold in the cooked brown rice and stir for 2 minutes until the rice is heated through and has absorbed the spices.
Remove from heat and drizzle with fresh lime juice, tossing everything one last time.
Garnish with freshly chopped cilantro and serve immediately while hot.
