Did this the other night... over Tilapia... but then ate some of it as a salad the next day.
1 large mango cubed
1/2 red bell pepper diced
1/2 or 1 avocado diced
1/2 a lime (just the fresh squeezed juice)
1/2 or 1 lemon (just the fresh squeezed juice)
canned cut corn (1/2 can or whatever you prefer)
mix - chill and serve.
I love it because it's fresh, zesty and matches are summer weather in March.
