This is as simple (and colorful) as it gets.
My friend Kristi recently gave me some watermelon radishes she got from a local farm as part of her CSA (community supported agriculture) delivery. I never heard of them and asked how to prepare them.
“Eat them raw,” she suggested. “They’re very good with hummus.”
So I washed and peeled them, and then sliced them into disks. They go well with hummus and make a colorful, healthy appetizer.
