I tried out this recipe today. Normally when I do this type of thing I just put in the pork roast, onions, and a store-bought sauce, but this was SO YUMMY I'm not sure I'm doing that anymore. I thought I had some apple cider vinegar, so I didn't buy any, but when I got to my pantry today all I had was basalmic vinegar. And it was delish. It didn't even really taste like basalmic vinegar either, so I don't think anyone noticed. I also used pre prepared mustard (spicy brown), too, instead of powdered.
Served it up with some steamed veggies, and it went over really well!
