Give it all to me! I love the stuff.
It is good in soup, or souffle, or stir-fry, or quiche. Or pie, with a cheesy sauce. Or very quickly fried up with ginger and garlic in sesame oil.
But - giving up meat doesn't mean giving up gravy and mash. There's no reason to not have veggie gravy. (If you're missing the meatiness, adding some or all of marmite, mushroom ketchup, and smoked paprika can help.)
