Cook corn in boiling water for 12 minutes. Once the corn is cool enough to handle, use a sharp knife and cut corn off the cob. Use the back of your knife and run the knife up and down the cob to remove the last bits of corn clinging to the cob.
Meanwhile rinse black beans and let drain until almost dry. Remove seeds from tomato and dice into 1/2 pieces. Dice onion. Rough chop washed cilantro.
Mix corn, black beans, tomatoes, onions, and cilantro in a large bowl. Drizzle with olive oil and season with salt and pepper.
