This is probably the simplest roast recipe there is.
2-3 lb deer roast
16 oz jar giardiniera (hot or mild depending on your taste)
Put the roast in a crock pot on low and dump in the jar of giardiniera. Cook for 6-8 hours. Slice the roast thinly and put on most any sort of bun. Spoon on some of the giardiniera if desired.
