I made this back in 2003 for a dinner party. Everyone loved it! You can adjust the amount of chilies for your taste.
2 cans of tomatoes with green chilies drained, retain the liquid
2 large cloves of garlic, minced
½ small onion, diced
1 small bunch of cilantro, chopped
2 medium hot green chilies, chopped
1 T. olive oil
Salt and pepper to taste
Combine all in a blender and process until the desired consistency. Add in some of the liquid from the canned tomatoes for a saucier salsa.
Serve with chips.
