This quick and easy salad is the perfect start to taco night. Better yet, toss this into a few tortillas — hard or soft, corn or flour, it's up to you — for a vegetarian taco filling. Top with some shredded Jack and Cheddar cheese and you're all set.
In a large bowl, combine the black beans, avocados, tomatoes, scallions, cilantro, and red onion, and toss with the Italian dressing. Serve with tortilla chips on the side.
