Begin by preheating your oven to 400 F.
Using a pot, heat up a small amount of cooking fat on medium-low heat. Add the garlic and cook gently until fragrant, which should take around 2 minutes.
2 tablespoon cooking fat, 2 cloves garlic
Next, add the tomatoes, dried thyme, and black pepper to the pot. Mix everything together well, and allow the mixture to simmer for about 10 minutes. While simmering, use a wooden spoon to break up the tomatoes. Once the tomato sauce has finished simmering, pour it into a baking dish.
16 oz whole tomatoes, 1 tablespoon dried thyme, Freshly ground black pepper
In a shallow pan, place the leek halves in water and bring to a boil. Let them boil for about 10 minutes, then drain.
1 lb leeks
Take the cooked leek halves and place them on top of the tomato sauce in the baking dish. Finally, spread evenly sliced bacon over the top of the dish.
10 slices bacon
Put the baking dish in the preheated oven and let cook for 20 to 25 minutes.
