This recipe is from The Healthy Kitchen, a cookbook written by Andrew Weil + Rosie Daley. This is one of the first cookbooks I ever bought when transitioning to cooking and eating healthy.
Trim the ends of the brussels sprouts and remove and discard any discolored outer leaves. If the sprouts are large (more than 1 inch in diameter), cut them in quarters lengthwise through the stem end. If smaller, cut them in half.
Bring 2 quarts of water to a boil, add salt and the sprouts. Boil the sprouts uncovered until they are just crunchy-tender (about 5 minutes). Drain the sprouts well.
Wipe and dry the pot and heat the olive oil over a medium heat. Add the red pepper flakes and garlic and saute for 1 minute or until fragrant. Add the sprouts and nutmeg and sauce for another minute. Mix the Parmesan cheese and toss the sprouts until the cheese melts.
