In a small mixing bowl, crack in the eggs and beat well.
Add spinach and Low FODMAP Certified Spice Mix (Mexican/Taco Seasoning Mix). Stir until well-combined.
Heat a large frying pan over medium-high heat and add 1 tbsp. of butter. Shake it gently to evenly coat the frying pan with the butter.
Now, pour in half a cup of the eggs on to the pan and move it back and forth to spread the eggs evenly on to the bottom of the pan.
Cook until completely done from one side. Then, flip it using a fork and let it cook from the other sides.
Once done, top it with 1 tbsp feta cheese, some fresh sliced tomatoes, and finely chopped spring onions. Now, fold it into one half and place it on to the platter.
Repeat the same procedure with the remaining eggs.
Once done, serve with bran bread slices, if desired. Enjoy!
