Add all the feta sauce ingredients to a food processor and blend until smooth. Set aside.
Mix the ground turkey sauce ingredients together and set aside.
Preheat your oven to 450ºF and line a half sheet pan with parchment paper. Toss the diced sweet potatoes with the olive oil and a pinch of salt and pepper. Arrange in an even layer on the sheet pan and bake for 25-30 minutes or until crispy.
Heat 1 teaspoon of olive oil in a large skillet over medium-high heat. Once hot, add the ground turkey and brown on one side for 3-4 minutes until a golden brown crust forms before adding the diced red onion and breaking the turkey apart. Continue cooking until the onion softens and the turkey is fully cooked, about 5-6 minutes.
Once the ground turkey is fully cooked, add the sauce and stir everything together. Cook until the sauce thickens and coats everything evenly, about 1-2 minutes.
While the turkey cooks, microwave or heat the rice according to the instructions on its packaging. (Or prepare your choice of rice ahead of time.)
Build each bowl with 155g (5.5 oz) of ground turkey, about 1 cup of the rice blend, 1/6th of the sweet potatoes, and 3 tablespoons (45g) of the sauce.
