Unroll the TODAY® Original shortcrust pastry and cut the sheet of pastry into 12 even squares. Line the muffin tray with the pastry squares.
Melt the butter in a frying pan, over a medium heat, sauté the mushrooms for 5 – 10 minutes until browned and cooked through and season with salt and pepper. Remove and set aside.
In the same pan, toss in the tomatoes and fry for 2 minutes. Set aside.
Place a couple of tomatoes, a few mushrooms, an egg, a sprig of thyme and a crumbling of feta into each muffin cup. Bake for 15 minutes, until the pastry is browned and the egg is cooked.
