Thinly slice the yellow onion and chop the bell pepper.

Brown the hamburger, adding salt as needed, and set aside. Do not drain away the oil from the pan.

Add a little oil and the yellow onion and, if fresh, the bell pepepr. If using frozen bell pepper, do not add until the onion is mostly done. Sautee. Add salt as needed.

Reintroduce the hamburger once everything is hot, thawed, and mostly cooked.

Add the seasoning mix and the water required for it, as specified on the package. Cook until reduced to a thick gravy.

Heat the tortillas on a plate in the microwave for 30 seconds with a moist paper towel on top of them.

Roll or fold, and enjoy!
