Combine sugar and cinnamon in a small resealable plastic bag.
Heat 1 tsp. oil in a frying pan over medium heat. Set 1 tortilla in pan and sprinkle half the tortilla with 2 tbsp. chocolate chips. Fold tortilla over and brown lightly on each side, turning once, 4 to 5 minutes total. Transfer to a cutting board and sprinkle on both sides with cinnamon sugar. Cut into wedges. Repeat to make more chocodillas.
*Bring packets of coconut oil, or seal oil in a small screw-on Nalgene bottle. Artisana Organics raw virgin coconut oil tastes dreamy and the packets don't leak ($23/10 packets, each about 1 oz.; natural-foods stores and amazon.com).
