Method
- Heat oil in a large skillet over medium heat until hot and shimmering but not smoking. Add onion and cook, stirring occasionally, until softened, about 4 minutes.
- Add the spice packet. Cook, stirring constantly, until fragrant, about 1 minute.
- Add ground beef and cook, stirring often, until it is no longer pink, about 5 minutes. Use a spatula to break up the block of meat into smaller pieces as you stir.
- Add tomatoes or tomato sauce, water, and vinegar. Bring the mixture to a simmer.
- Reduce heat to medium-low and simmer, uncovered, stirring frequently, until liquid has reduced and thickened. The mixture should not be completely dry. This takes about 10 minutes. Taste and adjust seasonings with salt.
- If you are using hard tortilla shells, toast them in the oven or toaster oven at 350ºF for about 2 minutes.
- If you are using flour tortillas, wrap them in foil and place them in a 350ºF oven for 15 minutes or until warm. You can also toast them in a toaster. Remove from the oven and transfer the tortillas to a tea towel to keep them warm.
- Place shredded cheese, lettuce, salsa, sour cream (if using), and avocado (if using) in separate bowls. Assemble your tacos as you wish.
