Step 1: Dice finely or grate tomatoes, saute on medium heat until almost all of the juice evaporates. Add the tomato paste and vegetable oil/butter and fry for 1-2 min.
Step 2: Crack the eggs and mix it with tomatoes on low heat and try to achieve a balanced, reddish color. Taste it, and then add the salt, pepper, and cinnamon, based on your taste.
Step 3: Slice the onion and make crispy, fried onion. You can saute, microwave, roast in the oven, or even use a pot full of boiling water and use its lid to make it oil-free.
Step 4: Put a generous amount of crispy fried onions on your omelet and serve it alongside flatbread, veggies (basils, garden radish, pickles, and raw onions).
