Preheat your oven to 400 degrees.
In a medium bowl, toss together the sliced tomato, turkey pepperoni, olive oil, 1 tsp Italian seasoning and ½ tsp Garlic Salt. Spread in one layer on a baking sheet and sprinkle with a pinch of pepper.
Bake until the tomatoes begin to soften, about 13-15 minutes. Note that the pepperoni will only take 6-7 mins to crisp up, so check them often and remove from the pan when done, continuing to cook the tomatoes until soft. Set aside
Bring a large pot of salted water to a boil, and cook the pasta according the package directions. Drain the cooked pasta and reserve ½ cup of the cooking water.
Transfer the cooked pasta back into the pot and stir in ¼ cup of the Pasta water. Then add in the cheese, a little bit at a time. Stir between each addition until the cheese is fully melted, and then continue to add the cheese.
Once the cheese is melted, stir in the Greek yogurt until creamy and well mixed. Stir in the remaining 1 tsp of Garlic salt and Italian seasoning and season with a pinch of pepper. If it’s too thick, add the remaining pasta water.
Stir in the cooked tomatoes and pepperoni and DEVOUR.
