Heat olive oil in a large skillet over medium-high heat until shimmering.
Add ground turkey to the skillet and cook for 7-10 minutes, breaking it into small crumbles, until no pink remains.
Stir in the oregano, garlic powder, onion powder, salt, and pepper; cook for an additional 2 minutes to toast the spices.
In a large mixing bowl, combine the warm cooked rice with lemon juice and chopped parsley, tossing to incorporate.
Divide the lemon-parsley rice equally among four meal-prep containers.
Portion the seasoned turkey evenly over the rice in each container.
Distribute the diced cucumber, halved tomatoes, and minced red onion into each bowl.
Top each bowl with 2 tablespoons of crumbled feta cheese and a dollop of tzatziki or hummus before sealing.
