Contains: tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Place the thinly sliced fennel and red onion in a bowl of cold water for 10 minutes to crisp them, then drain and pat dry.
Toss the sliced green apple with 1 teaspoon lemon juice so it does not brown.
In a small bowl, whisk together 2 teaspoons lemon juice, 2 teaspoons lime juice, 2 teaspoons grapefruit juice, and the extra-virgin olive oil. Season with salt and black pepper to taste.
In a large bowl, combine the fennel, onion, apple, and grapefruit sections.
Pour the dressing over the salad and toss gently to coat.
Add the chopped toasted walnuts and torn basil leaves, then toss once more.
Taste and adjust salt, pepper, or extra lemon or lime juice as desired before serving.
