5 Ingredient Mild & Fresh Sweet Onion Salsa Recipe
Snag a big bag of your favorite tortilla chips, because this salsa is irresistible! If you’ve ever had garden fresh gourmet mild sweet onion salsa – this one is better!
Plus you get to control what goes into your salsa – no citric acid or lime oil, we’re using real fresh lime juice for the best flavor!
Raw onions can give a really strong flavor to salsas, but since we’re opting to use sweet onion here, it’s milder and gives a sweet quality to this fresh dip.
While there are no jalapeno peppers in this one, you can add 1-2 in if you like a little heat.
It makes a big batch to enjoy all week long (it almost fills a large mason jar!). If you’re looking to make small batches, feel free to cut the recipe in half.
