- Mix the sugar, flour, mustard, vinegar and orange juice in a microwave safe bowl. Add the Smokies and stir until coated.
- Heat on high for 5 minutes. Check. If the Smokies are not heated through, heat more. Microwaves vary on heating, so go a minute until the appetizers are ready.
- These can also be heated in the crock pot if you have more time. Just let them simmer along until hot. This is about an hour on high or 2 hours on low.
