This is our go to recipe for a simple, fresh salsa that we put on most of our tacos and is great with chips. It’s probably the simplest and cheapest salsa you can make. You can add additional ingredients to add a bit of character to it. Chopped garlic, smoked salt, diced tomatillos, or honey would be great. You can roast the tomatoes and onions in your oven to add a deeper flavor.
