And, since I'd bought 2 lbs of sausage last week and only needed one for the quiche... and I still had a remaining can of Hunt's crushed tomatoes and a can of tomato paste left in my cabinet that I'd resisted throwing out or giving away.... I just went for it.
(Not quite sure why I took the picture so caddy-wampus.)
It actually turned out pretty good! I pretty much still browned the sausage, browned some bell peppers and onion in the sausage grease, then threw those back together and added in some crushed tomatoes and paste to thicken up a bit. Added a good amount of Italian blend seasoning. Then added about 6 eggs, mixed together really well, mixed in some Swiss and Cheddar (since I'm not supposed to have Mozzarella). Poured the mixture into a lightly greased casserole and topped with a little more cheese. Baked for about 40 minutes.
I think next time, I'd like to try an actual Paleo lasagne recipe... but this one wasn't too bad for an improvisational / trial sort of dish! It was definitely a welcome change from all the hamburgers I had the rest of the week!
