Really fresh, and something different!
Big can (14 oz) of rinsed black beans,
big can (14 oz) of Niblets corn (I read frozen peaches and cream corn is okay as well)
one each finely diced tomato and red pepper
Tennis ball sized red onion, diced and sprinkled with 1-2 tbsp granulated sugar to weep, then set in microwave for a minute (this takes the burn out of the onion so it stays down)
1/2 c lime juice
finely chopped fresh cilantro (half a bunch- maybe 1/4 cup worth?)
Let sit a bit for flavours to meld. May serve with taco chips to scoop. You could also put it into a taco bowl, or serve on lettuce.
