1. In a large bowl, add black beans, corn, cilantro, jalapeno, and tomatoes; fold gently to combine. Cut lime in half, then squeeze juice from both sides over the bean mixture. Sprinkle salt and pepper over the top; fold gently to combine.
2. Add avocado cubes and gently fold; careful, you don’t want to mash the avocado.
3. Garnish with additional cilantro if desired.
Notes: this salad is also delicious with some colby jack cheese or mexican blend shredded cheese added.
