Boil a large pot of water with the bouillon cube. Add the egg first, then the pasta. Cook until al dente. Pull the egg out into cold water and set aside. Save about 1 cup of the pasta water, then drain the rest.
Slice the frankfurters on an angle. Chop the onion, tomato, garlic, hot pepper, and bell peppers.
Heat the oil and butter in a large saucepan over medium heat. Fry the frankfurter slices until lightly browned.
Stir in the green seasoning and tomato paste. Cook about 1 minute, stirring, so the paste darkens slightly.
Add the onion and garlic and sauté about 1 minute. Add the tomato and hot pepper and cook until the tomato softens.
Add the bell peppers, Sazón, and complete seasoning. Mix everything well.
Pour in about 1 cup of the reserved pasta water. Cover and simmer 2 to 3 minutes.
Add the drained pasta and toss until every strand is coated. Slice the boiled egg and lay it on top, or mix it in. Serve hot.
