In a skillet over medium heat, sauté the chickpeas with a pinch of salt until they are slightly crispy. Set aside and let cool.
In a small bowl, whisk together the olive oil, vinegar, minced garlic, Dijon mustard, dried oregano, salt, and black pepper. Adjust the seasoning to taste.
In a large salad bowl, combine the chopped lettuce, sliced radicchio, chopped tomatoes, red onion, cucumber, celery, bell pepper, chopped olives, artichoke hearts, pepperoncini, fresh basil, and fresh parsley.
Toss the sautéed chickpeas, vegan parmesan or nutritional flakes, and diced mozzarella (if using) into the salad for an added crunch and protein.
Pour the dressing over the salad and toss gently to coat all the ingredients evenly.
Divide the Italian Vegan Chopped Salad into serving bowls and enjoy!
