Clean the endives. Remove the outermost leaves. Each endive should be cut in half lengthwise.
In a medium-sized saucepan, heat the olive oil or butter. Season with salt and pepper. Cook for approximately 5 minutes, turning the endives over a couple of times to brown them.
Mix in the nutmeg, garlic, and sugar. Cook for another minute or two, flipping them over once.
Cook over until the endives are soft, adding a little water as needed (about 10 to 15 minutes more). Flip them over from time to time to get all sides sautéed, but be careful because endives, like onions, like to come apart when cooked.
Season with salt and pepper to taste. Serve and have fun!
