Peel the onion and slice it into quarters.
Slice the bell peppers, jalapeño, and chili pepper open; carefully remove all the seeds.
Chop the tomatoes into quarters.
If using fresh garlic, peel and slice; or you can use already minced fresh garlic.
Place all the ingredients, including the onion, peppers, tomatoes, basil, garlic, and salt, in a blender.
Pulse the blender until the salsa has the desired chunky texture and consistency.
Serve with tortilla chips or whatever your heart desires.
