Ok, so several options here. I don’t get paid for any of these, but keto is my thing
Check out no carb bread on Amazon. There is several options, all pricey… But the zero carb brand will do the trick, not big slices
I highly highly suggest smart cakes for muffins, etc
Check out carbquick baking mix, everything runs a little dry, so need to work with it, but you can make anything bakery related with it.
And lastly. Miracle noodle. They are excellent and work for anything noodle related.
Tortilla wrap - ole foods makes a flax based wrap that comes in several flavors. They are excellent
All of these have been tested by me to not cause a huge spike of sugar, in fact some, since they are mainly fiber, actually slow things way way down, and fill you up more.
