Lunch - Avacado Corn Black Bean Salad

Today for lunch I made the avocado black bean salad I posted here.

I made one update. I added a splash of olive oil and a splash of vinegar and we ate it in Romaine lettuce leaves like a taco. It was amazing.

Here is the updated recipe:
2 ears of corn - boil then cut off corn
1 half a spanish onion diced
4-5 roma tomatoes (or their equivalent - we used giant beefsteak tomatoes in Florida)
1 Avacado cubed
2 cans of black beans rinsed
chopped cilantro to your liking
juice of one whole lime
splash of olive oil
splash of vinegar
black pepper
