In a large bowl, soak bulgar wheat in 6 cups of water for 1 hour, or overnight, then drain and set aside.
In a food processor, pulse bell pepper, onion, garlic, and parsley until it forms a paste and set aside.
In a large bowl, combine ground beef, vegetable paste, adobo, sazón, and salt. Set aside.
Mix the bulgar wheat with ½ of the beef mixture in a large bowl until fully combined, about 3 minutes.
Cook the remaining beef mixture in a pan over medium heat until browned, about 8 minutes. Add tomato sauce and raisins to the pan and cook until the liquid is absorbed, about 5 minutes. Remove from heat and let cool completely.
To assemble quipes, take 2 tbsp of the bulgar wheat mixture, roll into a ball, and make a hole in the center. Fill the hole with 1 tbsp of beef filling, wrap the bulgar wheat around the filling, and shape into a diamond with tapered ends. Place on a parchment-lined sheet and refrigerate for 20 minutes, or until solid.
Heat enough oil in a pan over low to medium heat to cover 1 inch from the bottom and let the oil get very hot before frying the quipes until browned on all sides, about 8 minutes.
Remove quipes from oil and place on a paper towel-lined plate. Let cool completely before serving. Buen provecho!
