Meanwhile, heat the olive oil in a large skillet over medium-high heat. Add onions and garlic and cook about 3 minutes or until the onions are soft and starting to brown. Add the ground turkey, 1/4 teaspoon salt, and 1/4 teaspoon black pepper and continue to cook, stirring occasionally, until the turkey is beginning to brown and cooked through. Stir in the artichokes. Remove from heat and let cool.
