These chili-beef-stuffed zucchinis are a delicious and healthy alternative to traditional stuffed peppers. The zucchinis are hollowed out and filled with a flavorful mixture of ground beef, onions, garlic, chili powder, and spices. They are then baked until the zucchinis are tender and the filling is cooked through. Serve these stuffed zucchinis as a main dish or as a side dish with a fresh salad for a complete and satisfying meal.
