Lunch Ideas

Wow, this looks really delicious! I will keep this in mind if I’m ever serving a bread-like to company. I would usually take the meat filling and eat it on top of salad and sometimes people make silly remarks about ‘how healthy’ it looks. Healthier than a burger bun for sure! But this looks sufficiently ‘unhealthy’ that people won’t pass remarks lol.

Is the cream of tartar absolutely necessary? I don’t have that in my kitchen and would have to buy it specially. Any possible substitute?
