First make your rye bread croutons. Line a baking sheet with foil. Place your rye bread chunks on the baking sheet and toss with melted butter. Put in the oven until golden brown.
While the croutons are baking, prepare your salad. I have found that if you’re serving a group of people, you can make a board and place each ingredient in separate bowls so that people can make their own individual salads. Or just combine all ingredients in one large bowl and toss.
