Dice the red onion, bell peppers, and cucumber into small, even bite-sized pieces.
Slice the Kalamata olives and finely chop the fresh parsley.
Drain, rinse, and dry the garbanzo beans and navy beans well.
Add the beans, chopped vegetables, olives, vegan feta, and parsley to a large mixing bowl.
In a small bowl or jar, whisk together the olive oil, lemon juice, maple syrup, Dijon mustard, garlic, salt, and oregano until smooth.
Pour the dressing over the salad and toss well until everything is evenly coated.
Serve right away, or refrigerate the Mediterranean Dense Bean Salad for later.
