1. Preheat the oven to 350°F and spray a standard 12-slot muffin tin with cooking spray.
2. Heat olive oil in a large skillet over medium heat. Once the pan is hot, add the chopped vegetables and sauté until they are cooked through and starting to brown. Remove from heat and set aside.
3. In a blender, combine eggs, dairy-free cream cheese, and salt. Blend until smooth, but do not overmix.
4. Distribute the sautéed vegetables evenly into each of the muffin tin slots.
5. Pour the egg mixture over the vegetables, filling each muffin slot evenly.
6. Carefully prepare the steam bath by placing a 9x13 or deep baking pan on the bottom rack of the oven. Boil water on the stovetop and carefully pour the boiling water into the pan.
7. Place the muffin tin on the middle rack of the oven. Close the oven and bake for 20-25 minutes.
8. Remove the muffin tin from the oven. Turn off the heat and allow the pan with the water to cool before removing it from the oven.
9. Allow the egg bites to cool slightly, then remove them from the muffin tin and enjoy!
