Sausage Breakfast Puffs

This has some my favorite flavors - Jimmy Dean sausage, eggs, cheese, onions, and mustard. I've made something this in a different form before - using an 8" round pan so it was like a casserole. I've been making a few things in my silicone muffin tins lately for two reasons: 1) each serving gets a tasty crunchy outside, and 2) I can make how ever many of them that fill up - rarely does every recipe I try come out to make exactly 12 of something. Now I have some leftovers, and I think they'll heat up just fine in the microwave at the office.
