Place a large, nonstick skillet on the stove at medium-high heat.
Add olive oil, ground beef, and seasoning when the pan is hot.
When there is no more visible pink in the beef, add the red onion.
Cook the beef and onion mixture until the beef is lightly browned.
Add the salsa, stir well, and cook for about one minute.
Add the coleslaw to the pan and stir well to combine.
Cook for 3 to 5 minutes, depending on how you like your cabbage.
Taste and adjust the salt.
Sprinkle the cheese over the top, cover the pan, and lower the heat.
The cheese should be melted after two or three minutes.
Garnish with the scallions and serve.
