Ground beef is one the most versatile dinner meats I can think of…(well, that, and chicken breasts. )
FAST
If you can’t think of anything else, you can always brown it with some onion and garlic, and make gravy by straining off the fat, then adding beef broth and thickening it with flour or cornstarch. Serve with mashed potatoes and vegetables and you have dinner in less than 30 minutes.
