This salsa recipe yields a medium-spicy flavor. For a milder version, use regular diced tomatoes instead of diced tomatoes with green chiles. To increase the heat, use a whole jalapeño or include some of the ribs and seeds-but be cautious, as that’s where most of the spice is concentrated.
Store homemade salsa in an airtight container in the refrigerator for up to 7 days.
