Here is one from my little "Southwest Ole!" cook book. It looks like most ingredients are standard (those mentioned above). I imagine it is a sort of "to taste" thing as the seasonings go. This recipe has some different items.

This one is called FIESTA SALSA

5 tomatoes, chopped
1 onion, finely chopped
1 bell pepper, chopped
1 (4-ounce) can shopped green chilies
1 tablespoon sugar
1 tablespoon red wine vinegar
1 tablespoon olive oil
1/2 teaspoon salt
1/4 teaspoon black pepper
3 tablespoons chopped fresh cilantro
1/4 teaspoon oregano

Mix all ingredients together. Refrigerate. Call me when it is ready!
