This recipe I tried on the fly--meaning I did not technically measure everything to specifics, but rather measured by taste. I included measurements for approximation, but please feel free to modify to what suits your taste buds.
In large bowl, combine ketchup, soy sauce, hot sauce, and brown sugar. Blend well until sugar dissolves, leaving no lumps. Adjust taste for your personal preferences, adding more or less of ingredients as necessary.
In an electric skillet or stovetop skillet/fry pan, place venison steak medallions in pan, and cover with seasoning mixture. Add any additional seasonings you wish (could be garlic powder, onion powder, chili powder, etc.)
Once meat is covered in seasoning mixture, cover and cook over low to medium heat (300 degrees if using electric skillet) for about 30 minutes or until done.
