Main filling

Method

Prep

  1. 1

    Slice onion thinly into half-moons until you have about 1 cup. Wipe mushrooms clean and slice thinly to yield about 1 cup. Mince garlic.

  2. 2

    Split hoagie rolls lengthwise but not all the way through so they open like a book. If desired, lightly butter or spray the cut sides for toasting.

Sauté onions and mushrooms

  1. 3

    Cook aromatics

    Heat a large skillet over medium heat. Add 1 tablespoon vegetable oil. Once shimmering, add the sliced onions and a pinch of salt. Cook, stirring occasionally, 6–8 minutes until onions are softened and beginning to caramelize.

  2. 4

    Add sliced mushrooms to the skillet with the onions and cook 4–5 minutes more until mushrooms release moisture and begin to brown. Push the mixture to one side of the pan.

Cook Impossible meat

  1. 5

    Brown the Impossible meat

    Increase heat to medium-high. Add the Impossible™ ground meat to the cleared side of the skillet (add a touch more oil if pan looks dry). Break it up with a spatula and cook 3–5 minutes, stirring occasionally, until it browns and resembles cooked ground beef.

  2. 6

    Stir the onions and mushrooms back into the meat. Add minced garlic, 1 tablespoon soy sauce, 1 teaspoon Worcestershire-style sauce, 1 teaspoon smoked paprika, 1 teaspoon onion powder, 1 teaspoon black pepper, and 1/2 teaspoon salt. Stir to combine and cook 1–2 minutes more so flavors meld and excess liquid reduces.

Assemble & melt cheese

  1. 7

    Portion filling

    Reduce heat to low. Divide the filling into four equal portions in the skillet, making shallow wells in each portion.

  2. 8

    Place one slice of white American cheese over each portion. Cover the skillet with a lid for 1–2 minutes, or until cheese is fully melted. If your skillet is too small to cover all portions, melt cheese individually using a separate small skillet or place under a broiler briefly—watch carefully to avoid burning.

Toast rolls & finish

  1. 9

    While cheese is melting, place hoagie rolls cut-side down on a second skillet or griddle over medium heat. Add 1 tablespoon butter (or vegan butter) to the pan and toast rolls 1–2 minutes until golden and crisp. Alternatively, toast under a broiler for 1–2 minutes.

  2. 10

    Using a spatula, transfer each cheesy filling portion into a toasted roll. Spoon any remaining pan juices over filling if desired. Sprinkle chopped parsley on top, close the roll, and serve immediately.
