Speedy 15-Minute Ground Beef Tacos

1.Heat the olive oil in a large skillet over medium-high heat. Add the chopped onion and cook for 2-3 minutes until softened.

2.Add the ground beef to the skillet. Break it up with a wooden spoon and cook until browned, about 5-7 minutes. Drain off any excess grease.

3.Stir in the taco seasoning mix and the water. Bring the mixture to a simmer, then reduce the heat to medium-low and cook for 3-5 minutes, stirring occasionally, until the liquid has mostly evaporated and the beef is well-coated and flavorful.

4.While the beef simmers, warm the tortillas according to package directions (usually by wrapping them in a damp paper towel and microwaving for 30-60 seconds, or briefly heating them in a dry skillet).

5.Assemble the tacos by spooning the seasoned beef mixture into the warm tortillas. Top immediately with shredded lettuce, salsa, cheese, and a dollop of sour cream or Greek yogurt.
