Beef and Vegetables

Cheese Sauce

Hoagie Buns

Method

Preparation of Beef and Vegetables

  1. 1

    Slice Ingredients

    Slice the beef sirloin into thin strips, and slice the bell peppers, onion, and mushrooms.

  2. 2

    Heat Oil

    In a large skillet, heat the olive oil over medium-high heat.

  3. 3

    Sauté Beef

    Add the sliced beef sirloin to the skillet, season with salt and black pepper, and sauté for about 3-4 minutes until browned.

  4. 4

    Add Vegetables

    Add the sliced bell peppers, onion, and mushrooms to the skillet. Cook for an additional 5-7 minutes, stirring occasionally, until the vegetables are tender.

Cheese Sauce Preparation

  1. 5

    Make Roux

    In a saucepan over medium heat, melt the butter. Once melted, whisk in the flour until smooth and cook for about 1 minute.

  2. 6

    Add Milk

    Gradually whisk in the milk, continuing to whisk until the mixture thickens (about 3-5 minutes).

  3. 7

    Add Cheese

    Remove from heat and stir in the shredded Swiss cheese and Monterey jack cheese until fully melted and smooth.

Assembling the Beef Philly

  1. 8

    Toast Buns

    Preheat your oven to 375°F (190°C). Place the hoagie buns on a baking sheet and toast in the oven for about 5 minutes until lightly crisp.

  2. 9

    Combine and Serve

    Spoon the sautéed beef and vegetable mixture into each toasted hoagie bun, then drizzle generously with the cheese sauce. Serve immediately.
