Heat the vegetable oil in a large nonstick skillet over medium-high heat. Add the onion and cook, stirring occasionally, until tender, about 4 minutes. Add the tomato paste, Worcestershire sauce, chili powder, cumin, coriander, paprika, oregano and garlic powder; cook, stirring, until the onion is coated, about 1 minute.

Add the beef, 1 teaspoon salt and a few grinds of pepper to the skillet. Cook, breaking up the meat, until no longer pink, about 5 minutes. Add the tomatoes, hot sauce and 1/4 cup water and bring to a simmer. Reduce the heat and cook, stirring occasionally, until the juices are slightly thickened, 5 to 7 minutes. Season with salt and pepper.

Meanwhile, warm the taco shells as the label directs. Fill with the beef mixture and top with lettuce, cheese and/or pickled jalapenos.
