Needed something to serve up quickly this morning and had to modify with what I had on hand, short-cut ingredients. Had pre-cooked microwave turkey sausage links, 1 can diced chilies, and 1 can of rotel tomatoes, and only had skim milk. I put the links in a processor to make crumbles and drained the rotel tomatoes. I didn't have overnight for it to sit in the fridge - which I assume is the reason these recipes always call for so much liquid. Or maybe more milk just stretches the eggs further, either way, it turned out fine. I reduced the cream/milk to 1 1/2 cups since it was going straight into the oven. I also used about half of the cheese and it was still verrry cheesy. I guess that amount is adjusted to your own family's liking. Added only a few extra spices, garlic powder, onion powder, pepper, but was surprised at how flavorful it was with very few ingredients. Just goes to show that simple can be amazing.

This was the perfect Christmas brunch. I've made a lot of different versions of this, but this is one of the best because I REALLY like cheese. I followed the recipe exactly and served it with my homemade salsa and pancakes (got a new Cuisinart Griddler and had to use it). I had to cook about 10 minutes longer, but I'm sure that's my crummy oven. Thank you, Little Bee. Edited to add: Had leftovers and threw them in the freezer in individual servings. Nuked it from frozen on auto defrost for about 4 minutes, then on high for 30 seconds. It was just as good as fresh. Yippee--another OAMC dish.

I've been making this for years and it is always a big hit. A couple suggestions. I use 10 eggs. Instead of bread crust, I use package of hash browns pressed into the bottom of the baking dish and then I brush on a little olive oil and lightly brown under the broiler. And I drain the green chilies for as long as possible. When I didn't drain them sufficiently, there was too much liquid in the bottom of the dish when serving (probably b/c I use hash browns instead of bread).
