Precook eggs for easy breakfast sandwiches. Crack an egg in each well of a muffin pan (use a little oil or butter if not a non-stick surface), add spinach (like shown) or just seasoning, cook at 350° for about 15 minutes. Keep in refrigerator for up to five days. Warm up in the morning, add to english muffin or toast, along with cheese if you want. Great back to school breakfast time saver! - This turned out pretty well, just make sure you really grease your muffin tin beforehand!
