Heat the olive oil in a large skillet over medium heat until shimmering and fragrant.
Add the ground turkey to the skillet, breaking it apart with a spatula as it begins to brown. Cook for about 5-7 minutes until no longer pink and the meat develops a light golden crust around the edges.
Stir in the minced garlic and red pepper flakes, cooking for another 30 seconds until the garlic is fragrant and slightly softened.
Add the sliced zucchini to the skillet, arranging them in an even layer. Cook for about 3-4 minutes, stirring occasionally, until they start to soften and develop some light browning.
Season with salt and pepper to taste, then continue cooking for another 3-4 minutes, stirring occasionally, until the zucchini is tender but still vibrant in color.
Remove the skillet from heat and give everything a final stir to combine the flavors. The mixture should be moist, with the zucchini cooked through but still holding some bite, and the turkey nicely browned and flavorful.
