This dish sounds marvelous to me. I am a vegetarian.
In my experience, most “regular meat eaters” (whatever that means) are not very likely to try something like this, they are too afraid of “weird ingredients” and they think they will die if they don’t eat meat at every meal.
Where I used to work, we would have regular potlucks, as one of the few vegetarians, I would always try to make things that were more “normal looking” so that the meat eaters would actually try some.
The only places I’ve been successful with serving any of the more “exotic vegetarian” dishes is in rooms full of other vegetarians, or at my own family’s potlucks. I am the only vegetarian in my family, and except for my Dad, everyone is very food oriented and loves trying new things. In general populations, such as work venues or at other parties (that are not my relatives) I have found that most people are very intimidated and sometimes even disgusted with the idea of eating anything vegetarian, to the point that they won’t even try something that they consider “weird.”
My standard vegetarian offerings for difficult crowds are: Greek salad (romaine lettuce, kalamata olives, sliced banana peppers, feta cheese, sliced tomatoes), pesto pasta salad (with cheese tortellini, grape tomatoes and broccoli, with jarred pesto sauce used for regular hot pasta), vegetarian chili and cornbread, hummus and pita chips, baked macaroni and cheese, tabouli, pasta salad (penne pasta, bean mixture with garbanzos and kidney beans, carrots and tomatoes in a vinaigrette) and Indian Samosas.
For whatever reason, people that are picky eaters tend to hate: tomatoes, onions, mushrooms, most green vegetables (especially Brussels sprouts) and beans.
And fearul meat eaters will balk at: tofu or any other soy-related product, most greens (spinach, kale, chard etc) but will eat iceberg and romaine lettuce, they might eat mushrooms on a pizza, but are not likely to eat something that is specifically made of mushrooms or filled with mushrooms, and pretty much any vegetable that is not extremely common (at least in the U.S.) like tomatoes, potatoes, corn and carrots, will not pass their lips.
Now here’s the ironic twist. At the place where I used to work, there were about 5 vegetarians (myself included) and the rest of the 80 person staff were not. So sometimes, the big boss would order pizzas and they would ususually get one vegetarian pie and 6 or 8 meat pies. Everybody would get in line to get some pizza and guess what? The vegetarian pie would be eaten first by the meat eaters. I can’t tell you how many times, us vegetarians didn’t get any pizza.
