• Adjust racks to top and middle positions and preheat oven to 450 degrees. Wash and dry all produce. • Cut potatoes into 1/2-inch-thick wedges. Halve, peel, and thinly slice onion. Halve, core, and thinly slice green pepper. Trim and slice mushrooms into 1/4-inch-thick pieces.

• Toss potatoes on a baking sheet with a large drizzle of olive oil, half the Fry Seasoning (you’ll use the rest in the next step), salt, and pepper. • Roast on top rack until golden brown and tender, 20-25 minutes.

• Meanwhile, heat a large drizzle of olive oil in a large pan over medium-high heat. Add onion, green pepper, and remaining Fry Seasoning; cook, stirring occasionally, until softened and lightly browned, 5-7 minutes. Season with salt and pepper. • Turn off heat; transfer to a plate. Wipe out pan.

• While veggies cook, in a small bowl, combine mayonnaise with mustard; season with salt and pepper. • Slice baguettes lengthwise, stopping before you get all the way through. Place cut sides up on a second baking sheet. • Toast on middle rack until lightly golden, 3-5 minutes.

• Heat a large drizzle of olive oil in pan used for veggies over medium-high heat. Add mushrooms and cook, stirring occasionally, until browned and crispy, 5-7 minutes. • Season with half the Bold & Savory Steak Spice (all for 4 servings) and salt; cook, stirring, until fragrant, 30 seconds. • Stir in stock concentrate and a splash of water. Cook until liquid has evaporated and mushrooms are saucy, 1-2 minutes. • Return veggies to pan.

• Keeping baguettes on sheet, spread insides of baguettes with half the Dijon mayo; fill with as many mushrooms and veggies as will fit, then sprinkle with mozzarella. (TIP: For an extra-saucy situation, use all the Dijon mayo on the hoagies.) Return sheet to oven until cheese melts, 2-3 minutes. • Divide hoagies and potato wedges between plates. Serve with remaining Dijon mayo on the side.
