We used to have a Don Pablos restaurant in town and we used to go there all the time. Sadly, it closed a few years ago, but I was excited to find this recipe for a copycat version http://www.recipezaar.com/Copycat-Don-Pablos-Salsa-130690
It was super easy to make and only took a few minutes to make. I used a food processor and it worked, but I would recommend using a blender instead if you have as it completely filled the food processor and was messy to mix and to pour into containers - if you use a food processor you might want to cut the recipe in half.
The cost was minimal - I estimate I spent less than $3 and ended up with two large jars that had previously housed 32 liquid oz of Walmart salsa.
When tomatoes are in season, I will use fresh instead of canned
Food processor or blender1 28 oz can diced tomatoes, drained (Approx. 3 1/4 cups fresh diced tomatoes)
1/2 cup onion (1 small or 1/2 medium)
1 1/2 cups water
1/2 teaspoon garlic powder
1/2 cup cilantro
1/2-1 teaspoon ground cumin
1 teaspoon salt
1 tablespoon sugar
2 jalapeno peppers (optional)
1 14-15 oz can diced tomatoes (Approx. 2 cups fresh diced tomatoes)
Remove seeds and chop jalepenos. You may want to use plastic gloves if they are very hot.
Put 1/2 cup of the diced tomato into the food processor or blender and puree. Once pureed, add all of the ingredients except the last can of tomatos and pulse until blended
Add the last can of tomatos and pulse until mixed. Pour into sterilized jars.
