In a large frypan over medium heat, combine the beef mince and onions. Cook, stirring frequently, until meat is no longer pink and onion is transparent, about 10 minutes. Remove from heat and drain fat. Season with all spice, salt and pepper; set aside.
Heat the olive oil in a frypan over medium heat. Stir in the pine nuts to coat with oil. Continue stirring until the nuts turn golden brown, about 2 minutes. Set aside.
Assemble by spreading half of the hummus over the bottom of a 23x33cm casserole dish. Tear the pita bread rounds into pieces and layer these over the hummus. Spoon the remaining hummus evenly over the bread and then top with pine nuts. Sprinkle with paprika, half the parsley and drizzle with lemon juice. Top with beef mince mixture and remaining parsley, then serve.
