Trim and rinse the radishes. Cut large ones into small pieces.
In a bowl, combine melted butter, honey, aceto balsamico, Vegeta, and a pinch of black pepper. Add the radishes and toss well to coat.
Transfer the radishes to a roasting tin and roast in the oven preheated to 220°C for about 15 to 20 minutes until done and crisp, stirring occasionally.
Serve the radishes on a bed of rucola and corn lettuce.
You can serve roasted radishes as a side dish with meat.
