Input: [header] How to eat nachos [title] Eat them while they are hot, and don't save them for later. [step] Nachos taste best while they are still warm. The longer you let them sit, the greasier they will become. <sep> (A) [title] Choose the type of nachos you want. [step] Tortilla chips are the most common variety but/or semi-chips are commercially available. (B) If you rush the nachos, they may not be ready while they are hot. [substeps] Make sure that you choose a topper. (C) Split open the side of the tortilla. [substeps] If it is hard to open the tortilla, it is better to use the inside as you will be able to see the spicy nachos inside the tortilla. (D) If you end up having any left over, it might be best to throw them away. Nachos don't reheat well, and usually turn into a greasy, gloopy mess.
Output:
D
