Step 1

• Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce. • Cut potatoes into 1/2-inch-thick wedges. Toss on a baking sheet with a drizzle of oil, oregano, salt, and pepper. Roast on top rack until browned and tender, 20-25 minutes.

Step 2

• While potatoes roast, peel and mince or grate garlic. Quarter lemon. Thinly slice tomato into rounds and season with salt and pepper. Pat chicken dry with paper towels; season all over with salt and pepper. Heat a drizzle of oil in a large pan over medium-high heat. Add chicken; cook until browned and cooked through, 3-5 minutes per side. Turn off heat; transfer to a plate. Wipe out pan.

Step 3

• In a small bowl, combine mayonnaise, mustard, 1/4 tsp sugar (1/2 tsp for 4 servings), juice from one lemon wedge (two wedges for 4), and a pinch of garlic. Season with salt and pepper to taste.

Step 4

• Heat a drizzle of oil in a large pan over medium-high heat. Add spinach and remaining garlic; season with salt and pepper. Cook, stirring, until spinach is wilted, 2-3 minutes. • Turn off heat. Transfer spinach to a second small bowl; stir in cream cheese until combined. • Wipe out pan. Use pan used for chicken here.

Step 5

• Spread half the sourdough slices with creamy spinach; top with even layers of feta, mozzarella, and tomato. • Spread remaining sourdough slices with Dijonnaise (save some for serving). • Close sandwiches. Top creamy spinach with chicken along with feta, mozzarella, and tomato.

Step 6

• Melt 1 TBSP butter in pan used for spinach over medium heat. Once hot, add sandwiches and push around in pan until melted butter has absorbed. (For 4 servings, work in batches or use a second pan, using 1 TBSP butter for each batch.) Cook until bread is golden brown and cheese is slightly melted, 4-6 minutes. • Add another 1 TBSP butter to pan, then flip sandwiches and push around again until melted butter has absorbed. Cook until bread is golden brown and cheese is fully melted, 4-6 minutes. TIP: If you have a heavy-bottomed pan, place on top of the sandwiches as they cook for a real panini experience!

Step 7

• Squeeze one lemon wedge over potatoes (two wedges for 4 servings). • Halve panini on a diagonal and divide between plates. Serve with potato wedges and remaining Dijonnaise on the side for dipping. Chicken is fully cooked when internal temperature reaches 165°.
