Here's a great summer salsa that's hearty enough to serve as a side dish or a salad.
3 tomatoes, diced
1 ear of corn, removed from the cob
1 ripe Haas avocado, pitted, peeled, and diced
1/4 red onion, finely diced
1 clove garlic, smashed and finely diced
1 handful of cilantro, finely chopped
juice of 1 lime
salt to taste
Place all ingredients in a bowl and stir to combine. This salsa gets better if it can sit for an hour or so to allow the lime to take some of the edge off the onions and to allow the flavors to combine. The lime should prevent the avocado from browning. Avoid refrigerating, as this will ruin the tomatoes and avocado.
