Toss ground beef with taco seasoning mix in a plastic resealable bag until coated.

Heat oil in a skillet over medium-high heat. Fry seasoned beef in hot oil, stirring occasionally, until beef colors.

Stir salsa, beans, and apricot preserves into the skillet with beef. Reduce heat to low; simmer until heated through, about 10 minutes.

Spoon 1/3 cup beef mixture into each taco shell and top with sliced olives.
