Prepare the Sloppy Joe Filling: Heat olive oil in a skillet over medium heat. Sauté the chopped onion for 2-3 minutes until softened. Add minced garlic and cook for 30 seconds until fragrant.

Add ground beef, season with salt and pepper, and cook until nicely browned.

Stir in tomato paste, ketchup, mustard, Worcestershire sauce, and brown sugar. Simmer for 5 minutes until the sauce thickens slightly.

Toast the Buns: While the filling simmers, toast the hamburger buns in a dry skillet or toaster until golden brown.

Make the Persian Cucumber Salad: In a bowl, combine all of the ingredients and mix until combined. Set aside.

Prepare the Pineapple Orange Juice Spritzer: In a pitcher, mix pineapple juice and orange juice. Add sparkling water and gently stir. Serve over ice cubes and garnish with an orange slice if desired.

Assemble and Serve: Spoon the sloppy joe mixture onto the toasted buns. Serve with the cucumber salad on the side and the spritzer.
