Place the 2 slices wheat bread quartered into the basket of your air fryer. Set the temperature at 400 °F and the cooking time at 3 minutes.
Make the salad while waiting. Add all of the ingredients to a medium/large bowl (11 oz avocado, 2 tbsp parsley, 1 tbsp cilantro, 1/2 tsp black pepper, 1 oz celery, 1 oz red onion, 1/4 tsp salt, 1 tbsp mayonnaise, 2 tbsp yogurt) and gently mix them up. Adjust the seasoning if needed.
Garnish with some cilantro leaves on top. Serve with toasted sprouted wheat bread or anything that floats your boat.
