Alpine Mushroom & Swiss Panini

• Toss potatoes on a baking sheet with remaining garlic powder, a drizzle of oil, salt, and pepper. • Roast on top rack until browned and tender, 20-25 minutes.

• Meanwhile, heat a large drizzle of oil in a large pan over medium-high heat. Add mushrooms and season with salt and pepper. Cook, stirring, until lightly browned, 4-5 minutes. TIP: Lower heat and add a splash of water if mushrooms begin to brown too quickly. • Add onion and another drizzle of oil; season with salt and pepper. Cook, stirring, until veggies are browned and tender, 5-7 minutes. • Stir in stock concentrate and 2 TBSP water; cook until water has evaporated and mixture is jammy. • Turn off heat; remove from pan and set aside. Wash out pan.

• Spread half the sourdough slices with mustard, then top with even layers of Swiss (tearing to fit if necessary), mushrooms and onion, and Monterey Jack. • Top with remaining sourdough slices to create sandwiches.

• Melt 1 TBSP butter in pan used for mushrooms and onion over medium heat. (For 4 servings, work in batches or use a second pan, using 1 TBSP butter for each batch.) Add sandwiches and push around in pan until melted butter is absorbed. Cook until bread is golden brown and cheese is slightly melted, 4-6 minutes.
