Mom's Quick Corn Salad (ready w/ pics)

There are a few things you need to know about my mom: She's not into cooking. She makes great banana bread. When she finds a recipe she likes, she makes it nonstop.
That third fact is why she is a gnocchi pro, and why I look forward to family barbecues. I love my family and all, don't get me wrong. But I really, really love her corn salad.

I have a weird memory of her getting the original recipe from something Paula Deen made, but because she's very into altering recipes, she made something better.
She always makes it with frozen corn, but because it's summer time and that means that freshly husked corn on the cob is pretty much mandatory, you can feel free to use that instead, just cut the corn off the cob instead of tossing a bag in the microwave. Other types of beans ca be subbed in too, depending on what you like and have on hand. We're a black bean family, but if you're the kidney or pinto sort, I'm sure that would be great too!

Probably would have been a better idea to take pictures before digging in. Oops

Mom's Corn Salad:
Serves an Army

6 cups frozen sweet corn (thawed, or fresh, cut off the cob and blanched for 4 minutes)
2 15oz. cans black beans, rinsed and drained
2 avocados, finely cubed
1 large red onion, chopped fine
2 medium tomatoes, chopped fine
1/4 cup olive oil
3 Tbs red wine vinegar
1/2 tsp lime zest
1 tsp cumin
1/2 tsp chili powder
Salt and Pepper to taste

Thaw your corn and place in a large bowl. If you're using fresh corn, cut it off the cob and blanch it in boiling water for 4 minutes. Transfer to an ice water bath tho stop the cooking and cool the kernels.
Drain your corn and toss with the beans. Gently fold in the onion, tomato, and avocado.
In a small bowl or measuring cup, mix the olive oil, vinegar, chili powder, cumin and lime zest.
Slowly mix the dressing into the salad, until the mixture is coated but not wet. Taste and season with additional cumin, chili, salt and pepper.
Chill the mixture for an hour, or until cold all the way through.
Serve and send the extras home with grandma!
