Instructions

1. Adjust rack to top position and preheat oven to 425°F. Wash and dry produce. Cut potatoes into ½-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. Trim and discard woody bottom ends from asparagus. (Save potatoes for another use.) Swap in asparagus for potatoes; roast until tender and lightly browned, 10-12 minutes.
2. While potatoes roast, peel and mince or grate garlic. Quarter lemon. Thinly slice tomato into rounds and season with salt and pepper.
3. In a small bowl, combine mayonnaise, mustard, ¼ tsp sugar (½ 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.
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.
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.
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!
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. Squeeze one lemon wedge (two wedges for 4 servings) over asparagus.

Recipe Tips

FAQ

Can I use a panini press instead of a skillet?

Yes! A panini press works perfectly. Preheat it, butter the bread and cook until golden and the cheese melts, about 4-6 minutes.

What can I substitute for feta cheese?

Goat cheese or ricotta salata are good alternatives. They provide a similar creamy and tangy flavor.

Can I make this recipe vegetarian?

It already is vegetarian! Just ensure your Dijonnaise uses vegetarian-friendly mayonnaise and mustard.
