To make healthy salsa at home, start with fresh ingredients such as tomatoes, onions, jalapenos, and cilantro. Avoid using canned or processed ingredients. Chop the ingredients finely and mix them together with a squeeze of fresh lime juice and a pinch of salt. You can also experiment with adding other herbs and spices such as cumin or paprika for extra flavor. Homemade salsa is a great way to control the ingredients and ensure that you are getting a healthy, flavorful condiment.
