We use crisp radishes for a bit of crunch and spiciness in this Crab Salad Sandwich. You can also use chopped fennel, celery, thinly sliced fresh apple, or matchsticks of jicama as alternatives.
Lemon juice adds bright acidity and makes all the difference in such a simple dish. Garnish with a slice of lemon to enhance the citrus effect. Serve with Cherry Tomato Caprese Salad.
