Served with warm tortillas and simple green salad.
Brown beef and onion together. Drain grease.
Add the rest of the ingredients to the browned meat.
Stir well.
Heat this mixture thoroughly.
Add more tomato sauce if the mixture is dry.
Cover and simmer for 20 minutes, or less if the mixture begins to dry out.
Warm the tortillas in a dry skillet for 30 seconds per side, and keep them wrapped in a towel until serving.
Make the salad: slice the cucumber and toss it with the spring mix, olive oil, balsamic vinegar, salt and pepper.
