JANE NOTE: I just used some shredded colby jack cheese I had in the fridge. So, I guess my frittata was not TRE formaggi, but it tasted good just the same
JANE NOTE: Yeah, Creminelli sausages are some expensive sausage you can order through WS. I just used regular old breakfast sausage and it was great.
Follow-up note, 1/23/09: I have since tried halving this recipe and it worked great. Just use two 9-10”³ skillets instead of 12”³. Works like a charm!
