This is gooood! This recipe is mostly from The Frugal Gourmet Celebrates Christmas cookbook, I added the garlic powder, you can eliminate it if you like. This goes good with Chumley's Horseradish Cream for Beef, #364510 and Blue Cheese Butter for Steaks, #364945. The ingredient measurements, you will have to play with, except for the pepper and garlic powder, I usually end up using more of the liquids and the mustard, you will see. The meat should be evenly coated (but not drowned) with the liquids and coated with the mustard (but not encrusted). I also stick toothpicks in the meat to make like coat hooks to hold the onions on. I use about 2 cups of onions, I'm an onion freak. Yes, the onions will be cremated, I'm warning you now, so don't write that up in a review, they still make a good garnish. I made this last Easter and my daughter's boyfriend's dad thought that I was going to throw them away, I told him no that this is the best part and he agreed. I use low sodium soy sauce but that is up to you. You can use whatever size roast you want, just adjust the seasonings and cook time,
