This is a very low carb preparation (therefore keto friendly) that's also rich in protein and doesn't have too many calories. It's also quite easy to prepare, except for the time spent coring and stuffing the mushrooms.
This is a very easy to make low calorie coconut flour cake with albumin powder (dried egg whites, which you can use for shakes or in recipe, you can even make snow whites if you mix the correct amount of water and whip it up 🥚🍰🥰) and sucralose.
Make it savory and you have a nice keto bread to fill
