Do let us know how the burger turns out! I'm curious myself! I still hate beans but I think I might be open to convincing...
I am so glad that Jack is so supportive. That's awesome! I think it surprises some people how good some of the alternatives or just the overall meatless meals can be. The obstacle to discovering that is an open mind (and an open mouth, heh). A friend of mine who is not veg but is a chef in one of the more popular restaurants where I live that is known for doing veg-friendly substitutes, remarked once that meat is mostly there to just take on the flavour of whatever it's cooked with. Seems a simple thing to observe but it really made me think! She elaborated by saying that if you can get the texture and the temperature right, then the rest will take care of itself. That's something I've tried taking forward with me in my own kitchen-related experiments and so far it has served me well!
Oh, and after being intrigued by some of the things you mentioned, Medusa (I'm so glad I'm not the only one who noticed these things!), I did some digging for some actual medical sources beyond some of the blog posts you typically see online (like journals, that sort of thing) which touched on how a vegetarian or vegan diet might affect the female body specifically and though a lot of what I found was guarded behind a paywall (

), I
did find a few for anyone who might be interested!
