• 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 crosswise into strips.

• Toss potatoes on a baking sheet with a large drizzle of olive oil, salt, and pepper. • Roast on top rack until golden brown and crispy, 20-25 minutes. • Meanwhile, in a small bowl, combine mayonnaise with 1/4 tsp garlic powder (add up to 1/2 tsp if you like; you’ll use more later). Season with salt and pepper.

• Heat a large drizzle of olive oil in a large pan over medium-high heat. Add onion and green pepper; cook, stirring occasionally, until softened and lightly browned, 5-7 minutes. Season with salt and pepper. • Transfer veggies to a plate.

• Meanwhile, place 2 TBSP butter (4 TBSP for 4 servings) and 1/4 tsp garlic powder (add more if desired) in a second small microwave-safe bowl. Microwave until just softened, 10 seconds. (TIP: Do so in 5-second intervals, checking in between, to avoid melting.) Season with salt and pepper; stir to combine. • Slice baguettes lengthwise, stopping before you get all the way through; spread garlic butter onto cut sides. Place cut sides up on a second baking sheet. • Toast on middle rack of oven until golden, 2-3 minutes.

• Pat diced steak* dry with paper towels; season generously with salt and pepper. • Heat a large drizzle of olive oil in pan used for veggies over high heat. Add steak and Italian Seasoning. Cook, stirring, until steak is browned and cooked through, 2-3 minutes. • Reduce heat to low and stir in stock concentrate and 2 TBSP water (4 TBSP for 4 servings). Season with salt and pepper. • Return cooked veggies to pan; stir to combine.

• Spread bottom halves of garlic buns with half the garlic mayo. Top with steak and veggie mixture, then sprinkle with mozzarella. • Return to oven until cheese melts, 2-3 minutes. • Drizzle with hot sauce if desired. Divide sandos and potatoes between plates. Serve with remaining garlic mayo on the side.
