If you have bison burger leftovers and veggies, I found a way to make a catsup-esque relish/dressing:
Saute a tsp of garlic powder in olive oil then add 1 part yellow peppers and 1 part tomatoes diced.
Throw in handful of chopped onion.
If translucent, put in enough red wine vinegar to get it simmering.
A teaspoon of mustard and a lil bit of cinnamon (yes, cinnamon) should be stirred in as well.
Let simmer as you chop up your greens.
