Fresh Tomato Sauce for Stuffed Squash

Make an ice-water bath: Fill a large bowl with ice and water; set aside. Bring a large pot of water to a boil. Place tomatoes in boiling water until skins just begin to loosen, 10 to 20 seconds. Remove; transfer to ice-water bath. Remove tomatoes from water, core, and peel. Slice tomatoes in half; remove and discard seeds and liquid. Cut the flesh into 1/4-inch dice.

Heat olive oil in a large skillet over medium-low heat. Add garlic cloves; cook until well browned all over, about 10 minutes. Add tomatoes; season with salt and pepper. Raise heat to medium; simmer sauce until tomatoes break down somewhat to a saucy consistency, about 15 minutes. Remove from heat, and discard garlic.
