1 (28 oz.) can crushed Italian plum tomatoes
1 medium onion
1 or 2 cloves garlic
1 tsp. oregano
1 tsp. salt
1 (4 oz.) can green chili peppers
1 or 2 jalapeno peppers*
1 tbsp. parsley (fresh, if possible)
1 tsp. ground cumin

Finely dice onion, chili peppers, jalapeno peppers and garlic. Sauté all ingredients except tomatoes. Add tomatoes and simmer 15 minutes. Cool in refrigerator uncovered. Serve with chips.

*You can increase the jalapeno peppers up to 6, for those who really like it "hot".
