I also have tons and tons of tomatos, and use them to make this salsa. I make the base and freeze it in zip lock bags, then in the middle of the winter, I pull a bag from the freezer and add the rest of the ingredents.
7 tomatos
3 dried chili de Arbol (these are small dried chilis, usually found in the ethnic section of your store)
1 head roasted garlic
Place the tomatos and chilis in a dry frying pan and let them go on low heat until the outsides are black and chared. They will pop and crack, but this is normal. Let them cool a little and then place them, the chilis and the roasted garlic in a blender and carefully blend until smooth. (this is where I bag and freeze it.)
When you want salsa, pull a bag from the freezer and thaw. Add 1 red onion, finely diced and a bunch of celantro leaves, chopped. A little splash of lemon or lime juice, some salt and pepper and it's time to enjoy!
