I LOVE this! The fennel bulb adds a delicate flavor. Adding the seeds further adds to the flavor of the fennel. I have used both fresh & frozen pearl onions, Using frozen pearl onions works out great without all the fuss of removing the skins off fresh onions. You can roast the onion & fennel bulb and make the buttery paste a head of time. Then combine with the hot green beans. Veggie amounts are flexible. This is amazing and a great side to serve with chicken, pork of beef. Source of Recipe: Inspired by Emeril & tweaked by Moi.
