Preheat oven to 425°.
Butter one side of the tortilla with butter and flip over the buttered side down on a baking sheet.
Place a measured amount of the meat filling in a vertical line down the middle of the tortilla. Continue with your rice, cheese, and extra jalapenos, if adding.
Fold the top edge of the tortilla into the middle, covering about ⅛-1/4 of the filling.
Repeat #4 for the bottom edge.
Brush the left edge of the tortilla with a little more butter. This will be your outside edge that keeps the burrito closed.
Turn the burrito 90 degrees so that the buttered edge is on the top (furthest away from you). Holding both the right and left sides, start at the bottom and roll the burrito away from you over top of the filling towards the buttered edge until you have a closed packet. This is usually two rolls worth.
Place the burrito seam side down on a buttered baking sheet.
Bake for 15-20 minutes until the burritos are toasted and golden brown.
