Start by gathering all your ingredients. Make sure everything is washed and ready to go. Chop the red onion, avocado, bell pepper, and green onions to your desired size. That bright red onion and green bell pepper will add wonderful colors.

In a large mixing bowl, combine the black beans, yellow corn, white corn, and Italian-style diced tomatoes. These ingredients form the delicious foundation of your salsa. Make sure to drain the beans and corn well before adding them to avoid excess liquid in your salsa.

Now, gently fold in the finely diced red onion, diced avocado, green onions, and red bell pepper. These fresh components offer crunch and brightness, lifting the overall flavor of the salsa.

Time to bring in those zesty flavors. Drizzle in the olive oil, sprinkle the ground cumin, and toss in the minced garlic and jalapeño. Don’t forget the freshly squeezed lime juice. This adds a refreshing kick that brings everything together beautifully.

Gently mix all the ingredients together until well combined. Be careful not to mash the avocado; you want those chunks to shine through! Finally, fold in the chopped cilantro for that fresh herbal taste.
