Wash the tomatoes and cut each one in half. Spread olive oil into a 9x12 glass pan. Add tomatoes. Sprinkle with salt and pepper. Press garlic cloves over the tomatoes and stir.
Bake in a 425 degree oven for 30 minutes, stirring occasionally as the juices caramelize.
When the tomatoes are roasted and the garlicky/tomatoey olive oil smells delicious, remove from the oven.
This sauce is delicious over pasta, in a pasta salad, over grilled vegetables, over a grilled fish, or scrambled into Sunday morning eggs. I keep whatever is left of the sauce in a recycled plastic tub in the fridge, where it keeps nicely for 2 days if there is any left uneaten.
