Gather all your ingredients first to ensure a smooth cooking process. Chop the vegetables finely and measure out spices. Preheat your oven to 375°F (190°C) and line your baking dish with parchment paper to prevent sticking.

In a large skillet, heat two tablespoons of olive oil over medium heat. Add minced garlic and diced onions, sautéing for about 3-4 minutes until they become fragrant and translucent.

Add your choice of protein to the skillet. Increase the heat to medium-high and cook for 5-7 minutes, stirring occasionally, until the meat is browned and cooked through.

Incorporate the chopped vegetables into the skillet, stirring to combine. Season with salt, pepper, and your favorite herbs, and continue cooking for an additional 5-6 minutes.

Pour in your choice of sauce and stir thoroughly, allowing the mixture to simmer for 3-4 minutes until everything is well-coated and heated through.

Transfer the mixture into the prepared baking dish, spreading it evenly. Top with cheese if desired, and bake for 20-25 minutes until bubbly and golden on top.

Once baked, remove your dish from the oven and let it cool for a few minutes. Garnish with fresh herbs for an added touch before serving.
