This recipe comes from Claire’s Corner Copia Cookbook: 225 Homestyle Vegetarian Recipes from Claire’s Family to Yours. We started making it when I couldn’t have vinegar, but it is better and cheaper than store-bought salsa.
1/4 cup olive oil
1 onion, chopped
6 cloves garlic, crushed
2 tsp chili powder
1/4 tsp crushed red pepper
4 oz can chopped green chiles
28 oz can diced tomatoes
1/2 cup chopped fresh cilantro
Heat oil over low heat and add onions and garlic. Cook for 15 minutes, stirring occasionally, until soft. Add remaining ingredients, plus salt and pepper to taste. Simmer for 30 minutes.
Makes about 1 quart.
