Zucchini
Diced tomatoes (canned or fresh)
Tomato sauce
Italian seasoning
Salt and pepper
Shredded cheddar or mozzarella cheese
Optional: breadcrumbs or crushed crackers for topping

Directions

Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Heat olive oil in a large skillet over medium heat. Add ground beef and cook until browned, breaking it apart with a spoon. Drain excess fat if needed.
Stir in diced onion and garlic, cooking until softened.
Add diced zucchini, tomatoes, tomato sauce, Italian seasoning, salt, and pepper. Cook for 5–7 minutes until zucchini begins to soften.

Sprinkle shredded cheese evenly over the top. Add breadcrumbs or crushed crackers if using.
Bake for 20–25 minutes, or until the cheese is melted and bubbly.
Let cool slightly before serving.

Swap cheddar for mozzarella, Monterey Jack, or a cheese blend.
Mix cooked pasta into the beef mixture before baking for a heartier meal.
Make it low-carb by skipping breadcrumbs and using extra cheese topping.
