How to Make It
Preheat the oven to 450°. On a large rimmed baking sheet, drizzle the kohlrabi with olive oil and season with salt and pepper. Roast for about 1 1/2 hours, until charred on the outside and tender within. Let cool slightly, then peel.
Arrange the kohlrabi on a platter. Generously drizzle with olive oil and season with salt and pepper. Sprinkle with the feta, jalapeños, thyme and sesame seeds and serve.
