Roasted Radishes
Radishes transform into something completely unexpected in the oven — they lose their peppery bite and become tender, mellow, and slightly sweet, almost like roasted new potatoes. A hot oven, a simple toss with olive oil and herbs, and about 25 minutes is all it takes. A wonderful low-carb side dish that will convert even radish skeptics.
