So, here is the first answer to the December meme that's going around. The original question was:
Do you have any experience with therapy or service dogs?
UNfortunately no, but I always thought it was a great idea. I expect that you are going to love doing this.
Since that wasn't much of an answer, I will move onto your alternate question:
Please explicate at length about vegetarian or vegan Jew food?
The dish you're thinking of making (pearl barley with mushrooms) sounds quite tasty, however as it so happens, one of my all time favorite Jewish dishes is vegetarian and can be made in a vegan version.
The dish? Kasha Varnishkes.
Now, I have no idea what a varnishke is, but kasha is buckwheat groats. Kasha has a delicious, nutty flavor when cooked and I highly recommend it! here's a recipe
. I'll add a few comments. I would make it with a vegetable stock, not pasta water.
Here's a slightly different version, which toasts the kasha in the oven. We always did it with an egg in a skillet, but this version is easier to make vegan
I like to add sauteed mushrooms in with the onions. And of course, the noodles have to be bowtie shape!
