Prepare the Sandwich Base
Preheat your oven to 375°F (190°C). Slice the French bread or baguette into two equal slices and place them on a baking sheet.

Warm the Prime Rib
Slice the cooked prime rib into thin slices. Place the slices on top of the bread on the baking sheet. Warm in the oven for about 10 minutes, or until heated through.

Crispy Onions Preparation

Prepare the Onions
While the sandwich is warming, soak the thinly sliced onions in buttermilk for at least 10 minutes.

Coat the Onions
In a mixing bowl, combine the flour, salt, and black pepper. Remove the onions from the buttermilk, letting excess drip off, and dredge them in the flour mixture until fully coated.

Fry the Onions
In a large skillet, heat the vegetable oil over medium-high heat. Once hot, carefully add the coated onions in batches, frying until golden brown and crispy, about 3-5 minutes per batch. Remove and drain on paper towels.
