Flatbread Pizzas with Roasted Tomatoes, Mozzarella and Spinach

These days I'm on a mission to use up the things I've thrown in my freezer. We had three bags with one or two flatbreads in them leftover from my recent love of the grilled chicken Caesar flatbreads. I saw a recipe for 5-Minute Flatbread Pizza with Prosciutto, Arugula, and Mozzarella in my blog reader and decided to combine that recipe with the always-delectable Roasted Tomato, Mozzarella and Spinach Sandwich.

The result was positively delicious. I love revisiting favorite recipes but it's also great to reinvent them to use up ingredients. When I make the grilled chicken caesar flatbreads I spread butter on the bread before I grill it. Everything is better with butter and it imparts such an amazing flavor that I decided to do that with these. The roasted tomatoes are always delicious and you can't go wrong with melty fresh mozzarella.

We really enjoyed these and I can't wait to make them again.

Flatbread Pizza with Roasted Tomatoes, Mozzarella and Spinach
Inspired by Serious Eats and Kate's Recipe Box

1lb plum tomatoes, halved
1 tablespoon olive oil, plus more for drizzling
Thyme sprigs, chopped
Salt and pepper
1 cup baby spinach, coarsely chopped
Extra virgin olive oil
Fresh lemon juice
Kosher salt and freshly ground black pepper
Spreadable butter
4 flatbread pita rounds, whole wheat or regular
8oz fresh mozzarella, sliced

Heat oven to 400F degrees. Lay tomatoes, cut side up, in a roasting pan and drizzle with 1 tablespoon olive oil. Sprinkle with thyme leaves, salt and pepper. Roast for 30-45 minutes. Allow the tomatoes to cool and then smash with a potato masher. If you don't like tomato skins, remove the skin after smashing.

In a small mixing bowl, dress the spinach with some extra-virgin olive oil, lemon juice, salt and pepper and set aside.

Heat a 12-inch skillet or a grill pan over medium heat until hot. Spread some butter over both sides of each flatbread. Add the flatbread to the skillet or grill pan and cook until browned, about 2 minutes. Flip and then immediately top with the cheese and tomatoes. Cover and cook until the cheese starts to melt.

Slide the pita out, place on a serving plate and keep warm in the oven while you cook the remaining batches. Top pizzas with the dressed spinach and cut into wedges. Serve immediately.
