I had this last night with some tortilla chips...
Corn and Black Bean Salsa

1 can corn, drained and rinsed (or about 1 1/2 cus fresh off the cob)
1 can black beans, drained and rinsed
1 medium onion, chopped (about 1 cup)
5 or 6 roma tomatoes, peeled, seeded and chopped
1 bunch cilantro, stemmed and chopped
5 or 6 cloves garlic, minced or smashed
2 or 3 jalapenos, depending on your preference, chopped
juice of two lemons, some zest too if you like the extra zing
salt, to taste, none of that iodized stuff, it throws off the taste
pepper, freshly ground, to taste
crushed red pepper flakes, for extra kick if you like

Mx all ingrediends and chill overnight.
