Pop the viennas on a plate and heat in the microwave for about 1-2 minutes or until heated through. Or alternatively warm them up in hot water on the stove, just make sure water doesn’t boil. You don’t want popped hot dogs!

Assemble viennas in buns and place in a baking dish. Spoon chilli evenly over hot dogs then top with cheese.

Cover dish with aluminium foil (tenting if necessary to keep the foil from touching the viennas) and bake at 350 degrees for 15- 18 minutes or until cheese is melted. Uncover and serve.
