In a skillet over medium-high heat, brown the ground beef until fully cooked, approximately 7 to 9 minutes.
Drain excess fat, stir in the taco seasoning and water, and simmer for 2 minutes until thickened.
Place a flour tortilla on a flat surface and distribute 1/4 cup of cheese in the center.
Add 1/4 of the beef mixture over the cheese, then top with another 1/4 cup of cheese.
Fold the edges of the tortilla toward the center to create a sealed hexagonal or square pocket.
Heat vegetable oil in a clean skillet over medium heat and place the pockets seam-side down.
Sear for 2 to 3 minutes per side until the exterior is golden brown and the cheese has melted.
Serve hot with sour cream, shredded lettuce, diced tomatoes, and jalapeƱos.
