Preheat your oven to 180°C/350°F/Gas 4. Spray 8 wells in a muffin pan with nonstick baking spray and set it aside.
Place the eggs, heavy cream, scallions, spinach, feta, and parsley into a large mixing bowl and whisk to combine. Season to taste with salt and pepper.
Divide the muffin mixture between the 8 muffin cups and top each muffin with 2 cherry tomato halves.
Place the muffin pan in the preheated oven and bake for 15-20 minutes or until the muffins are set and golden brown around the edges.
Remove the cooked muffins from the oven and cool them completely before removing them from the muffin pan. Enjoy!
