This hearty sandwich comes together with fresh french bread and homemade onion rings. The onion rings are so light and crispy and make the perfect topping for a hot roast beef sandwich.

- For Onion Rings:
- 1 large onion cut into thin slices
- 1 1/4 cups all-purpose flour

- Slice beef into thin pieces, using my electric knife works awesome for this job.
- Place roast beef slices into roasting pot, pour in left-over au jus or prepared gravy, mix together and warm up in oven for 30 mins. at 300 degrees.
- If your au jus is too thin, thicken with a bit of gravy thickener, before adding beef.
- Turn temperature to low and keep warm until ready to use.
- Prepare onion rings while the beef warms up.
- Heat the oil in a deep pot (you can also use a deep fryer)
- Separate the onion slices into rings, and set aside.
- In a small bowl, stir together the flour, baking powder and salt.
- Dip the onion slices into the flour mixture to coat; set aside.
- Whisk the egg and milk into the flour mixture using a fork.
- Dip the floured rings into the batter to coat.Then dip into the bread crumbs
- Fry in oil until golden brown 2-3 minutes
- Remove to paper towels to drain.
- Assemble by cutting thick slice of French bread, top with slices of roast beef, cover with gravy and top with onion rings.
