Texas caviar

My Uncle Russell is a great cook and Aunt Linda knows how to please a crowd what with all the bunco nights, baby showers and gatherings at her place. They brought this dip to a family party and it's awesome. I've been making it a lot lately with all of our ripe tomatoes. I really need to get more recipes from them. 

Roasted Corn Salsa (aka Texas Caviar)
1 16 oz bag frozen corn
6-8 roma tomatoes, diced
1 small onion diced
1 15 oz can black beans, rinsed
1 clove garlic, minced
3 avocados, diced
Juice of 3 limes
1/4 to 1/2 C fresh cilantro, chopped
1/4 C olive oil
1 tsp cumin
1 Tb red wine vinegar
salt and pepper to taste

Thaw corn on cookie sheet and broil until it begins to brown (or buy pre-roasted corn at Trader Joe's). Saute onions unless you like them raw. Mix all the ingredients with corn and let the flavors blend several hours. Serve with tortilla chips.

Serves 12 or so. Great for a potluck and keeps pretty well in the fridge for a couple of days.
