Preheat a grill for medium-high heat direct cooking.
In a medium-sized bowl combine the olives, roasted red pepper and parsley. Set aside.
In a large bowl combine the ground chuck, Lipton® Recipe Secrets® Onion Soup Mix and the chorizo. Shape into 8 equal-sized ½ inch thick patties.
Transfer the patties to the grill and cook on each side for 3 to 4 minutes, until well browned.
Top each patty with a slice of Manchego cheese and cook until the burgers are cooked through and the cheese is melted.
Put 1 tablespoon of the olive mixture on the bottom of each hamburger bun.
Top with a burger patty, another 1 tablespoon of the olive mixture and then with a bun top.
Repeat until all burgers are made.
