Sandwiches are not quite the same as they used to be, without the bread and all, but I improvise. Left over pancakes and waffles made from almond butter/flour or coconut flour are excellent replacements for us. Bacon, egg and cheese, tuna melts, BLT, egg salad, chicken salad, BBQ pork and sloppy joes, just a few tweaks and we can enjoy our old favorites.
I prefer to make a batch of bread specifically for sandwiches and leave out the sweetener. Actually, I minimize the sweetener in most of these recipes because sweet breakfasts' do not appeal to me lately.
Here are a few “bread” recipes I have had success with;
Toasted Coconut Waffles (sub honey for agave and use half as much)
