Preheat your oven to 350° F.
Chop your basil and tomatoes and set aside.
In a large bowl, whisk together the eggs, water or non-dairy milk, salt, and pepper. Then fold in the chopped basil and tomatoes.
Spray your muffin tins with some non-stick spray. Carefully fill the muffin tins about 3/4 full.
Put the muffin trays in the oven and allow them to cook for about 25-30 minutes. Remove from the heat, allow it to cool, and remove from the tins.
Store in an airtight container in the refrigerator. To reheat, heat in the microwave for 1-2 minutes or until desired temperature.
