I don't do bread or sweet substitutions that often. For me it is anything that is too delicious (hyper palatable) leads to too much eating, even if low carb.

I will do sweets for the holidays or a specific event where I want something special I can eat. I always make a pumpkin cheesecake for Thanksgiving.

For bread, I make oopsies and keep in my freezer for times when I want a sandwich or hotdog or somesuch to eat with the family or on a picnic. But half the time I forget about them and just eat a lunch meat rollup.

My husband is not quite on the low carb band wagon because he doesn't want to give up tortillas or buns (he will sometimes do lettuce wrap burger). He doesn't like the taste of oopsies - too eggy. I might have to make him those biscuits!

I've done savory minute microwave muffins before. But find them to be too filing and heavy to use to make a sandwich or for a bun.
