Good afternoon. This is my first post so I hope you don't mind me just jumping in - I've been a lurker for a long time though. I've been a T2 for about 23 years and recently gone onto insulin, so I'm starting over in terms of the way I now approach my diabetes and have recently started LCHF (at my age it is taking a while to think that butter etc. are okay to eat) - although not as enthusiastically as others (yet) - I'm just titrating my insulin up and coming off meds, so am doing everything gradually just now. I think, at 7 weeks, I'm finally starting to feel the benefits.
This doesn't answer the OPs actual problem, but thought it a good place to add it in view of other comments. I'm cutting out most carb based foods, but also looking at better ways of doing some dishes with many less carbs (my husband has to be able to enjoy them too) and pizza is one of the meals I'm happy that I've come to a compromise on.
I think I picked up the recipe here for chickpea flour pancakes - it's basically just chickpea flour (also called gram, besan or garbanzo flour) and water, with your choice of seasonings and a little baking powder - I add a dollop of yogurt to enrich it a bit. You just make a batter with the flour and water and let it sit a while and then make pancakes just as you would with a flour, egg and milk batter. I then use these as a base for some tomato puree and lots of chopped veggies and whatever I have in the fridge, like chorizo etc. Top with cheese - I tend to mix mozarella and strong cheddar and pop under the grill. I make mine with a small omlette pan that's about 7-8" in diameter and calculate the bases are about 9g of carbs each (depending on how thick you make them), plus whatever is in your toppings. Significantly less than flour based pizza dough. You can't eat them as finger food, they're too flimsy, but good with a knife and fork.
