This is the one I use for salsa to can.

2 28oz can crushed tomatos
1 finely diced seeded jalapeno
3 tsp salt
2 tsp cumin
dash black pepper
1 small-medium onion, finely chopped
2 cloves garlic, finely minced
2 tbsp lemon or lime juice
1 medium bunch fresh cilantro, tops only, chopped finely

Blend it all together and enjoy. To can, I use the recipe from the Ball Blue Book for their salsa recipe.

To make a BIG batch, I use 2 #10 cans and scale everything else accordingly. This makes some seriously good salsa, but it's not the thick and chunky kind.
