Dice the onion, pepper and tomato relatively small.
Warm the oil in a small skillet and add the onion and pepper. Cook a couple minutes until the onion softens.
Add the tomato, cumin, paprika, oregano, salt and pepper and cook for a few minutes so everything softens together. The tomato should become pretty sauce-like.
Add the eggs to the skillet and stir so that the eggs break up, mix in and start to cook. Take off the heat a little before the egg is fully cooked (there should still be a good amount uncooked) as they will continue to cook after it is off the heat.
