I threw this together last night and am enjoying it today with crackers.
1/2 granny smith apple, peeled and diced
1 mango, peeled and diced
1 peach, diced
3 persian cucumbers, diced (or part of one regular / English cucumber)
1/4 cup roasted corn kernels
dash of salt
2-3 Tbsp lime juice
A few mint leaves, chopped
Mix everything together in a bowl and allow to sit for an hour or so; tastes best the next day. Eat with tortilla chips or crackers, or serve on fish tacos or salad.
