Black bean and corn salad. Recipe follows...

In a bowl, toss together:
1 can of black beans, drained & rinsed
1 can of corn kernels, drained
1 small to medium red onion, diced
1 avocado, diced
some sprigs of cilantro, chopped
juice of half a lime (more or less according to taste) salt and pepper to taste

The salad can be either enjoyed by itself, wrapped in a tortilla shell, or wrapped in a romaine lettuce leaf like the Vietnamese.

Sounds yummy!
