@Rotergirl -- Have you seen the turkey bacon and turkey sausage available? It's really good and great for people who are watching their fat and cholesterol intake. And of course, there are always egg substitutes if this an issue.
My husband also likes the vegetarian sausage and bacon. I've tried them and they're pretty good, particularly the sausage. Enough red pepper flakes can disguise nearly anything. I've also heard of people "scrambling" soft tofu as a vegetarian option for eggs. Never tried that, though.
I'm still waiting on scientists to come up with a carb-free doughnut. I can dream, can't I?
