So often egg recipes recommend serving a green salad alongside to cut through richness and add a healthful element. Here, there’s no need, since this egg-dish does double duty: it is rich and satisfying, but also gets in a hefty serving of greens. There’s both Swiss chard, plus a cup each of chopped parsley and cilantro folded into the frittata. Any leftovers would make a killer breakfast sandwich. Layer with a spicy mayo (just stir hot sauce and mayo together) and pile onto buttered toast. Bonus points for throwing some bacon or sausage into the mix.
