I usually serve pot roast sandwiches with Israeli salad, but French fries would be fabulous. Because, well, French fries.

Pot Roast Sandwiches
Pot Roast Sandwiches are a delicious way to use up leftover pot roast and get dinner on the table in about 15 minutes.
Ingredients
- 1 large yellow onion
- 2 tablespoons vegetable, canola oil, or extra virgin olive oil
- 4 thick slices of hearty bread (I like to use sourdough)
- ¾ cup mayonnaise
- 1 teaspoon minced garlic
- ⅓ cup fresh parsley, chopped fine
- ⅓ cup fresh cilantro, chopped fine
- 16-20 ounces leftover pot roast - OR 1 pound deli roast beef
- 8 ounces gruyere cheese, sliced very thin
- 4 cups dark leafy greens, like spinach or kale
Instructions
- Preheat your oven's broiler.
- Cut a large yellow onion in half remove the outer layers of papery skin, and slice it into thin slices that are about ¼ inch thick. Pour 2 tablespoons of oil into a large skillet and add the sliced onions. Set the pan over medium heat and cook the onions, stirring them frequently, until they are soft and light golden brown. Scoop them onto a plate and allow them to cool slightly.
- Toast the slices of bread and lay them side by side on a baking sheet.
- Stir the garlic, parsley, and cilantro into the mayonnaise. Spread a generous layer of the herbed mayonnaise over each slice of toasted bread.
- Layer the onions and then the pot roast onto the sandwiches and top with a few slices of cheese.
- Place the sandwiches under the broiler to melt the cheese. Watch carefully - the cheese will go from just starting to brown to burnt very quickly.
- Remove the sandwiches from the oven, distribute among 4 plates, and top each with a generous portion of kale, spinach, or other dark leafy greens.
