You can use the Beyond sausages or the Field Roast brand ones that they sell in grocery stores. I'm pretty sure that the Field Roast brand is vegan. Not sure about BeyondPain.
I am not fond of toothaches. It's more fun to make cat food and dog food right now. I give up.
This too shall pass.
Mmmmm....sausage, apple and sage pie.....I never thought about combining those flavours. It sounds good. Do you have a recipe I can veg*nize?
