Prebiotic vegetables create a favorable climate in your gut for probiotics (good bacteria) to grow. Among prebiotic vegetables are: leek, onion, garlic, chicory and fennel.

This dish has leek, fennel and chicory. The white and light greens color beautifully with the drizzled olive oil.

Keep it really simple: slice the veggies in halves lengthwise, brush with olive oil and put in the oven on 180 degrees Celsius for about 30 minutes or until some ends start to color brown.

For serving, drizzle with olive oil, salt and pepper.

Great with bread.
