Toss lettuce and arugula in a bowl.
Add chickpeas, apple, brussels sprouts and avocado and toss again.
Make dressing by adding lemon juice, honey, mustard and vinegar into a small bowl.
Slowly add olive oil until it is at a consistency you like. I added a bit less than 1/2 a cup.
Salt and pepper to taste
Toss the salad with the dressing and enjoy!!
