In a braiser or large saucepan, add olive oil, cherry tomatoes, olives and garlic. Add the Feta cheese block in the center of the braiser and sprinkle with oregano and black pepper.
Bake for 20-30 minutes until the feta cheese has browned at the edges and cherry tomatoes have cooked down. During this time, cook your pasta and chop spinach. Set aside.
Once baked feta is done, remove braiser from oven and mash everything up with a fork. Be careful when mashing the hot cherry tomatoes. Add the cooked pasta in the feta mixture and add the fresh chopped spinach. Mix everything and serve.
Tip: This recipe does not require any additional salt as the feta and olives are salty. Ensure your saucepan is rated for 400 ℉ oven temperature.
