Cut one large tortilla into quarters and then set aside with the other 4 large whole tortillas.
Cook the chicken and onion
Preheat the Blackstone griddle to medium high heat.
Add a drizzle of oil and then the onions. Let cook for 4-5 minutes.
Stir the onions, squirt with water, and cover with the cooking dome.
Add a drizzle of chicken to the griddle and then add the chicken. Cook for 3-4 minutes per side, flipping once. Remove the onions and chicken from the griddle and leave it on medium heat. (Or, alternatively turn it off and then turn it back on if you think assembly of the crunchwraps will take longer.)
Assemble the wrap
Spread 2 tablespoons of sour cream in the center of the wrap followed by 2 tablespoons of salsa.
Add cheese, chicken, onions, tomato, Doritos, and then more cheese.
Add one of the tortilla quarters on top of all the fillings.
Fold the crunchwrap
Pretending that there are 6 'sides' to the round tortilla, you will make six fold into the center. Start with the bottom and fold one side in and over the quartered tortilla. Repeat 5 more times until the whole wrap is sealed. Turn it over to keep it sealed until you cook it.
Crisp the crunchwraps
Add the crunchwraps seam-side down to the hot griddle. Cook for 3-4 minutes per side, or until browned and crispy. Serve hot.

Notes
Using tools when cooking on a Blackstone grill makes some methods easier. I like to use a water bottle and dome for steam ingredients. When the onions have some color on them, squirt them with water and cover them with a dome to steam them. This helps lift flavor off the grill and soften the onions, helping them cook faster.Crunchwraps are best assembled as needed but the ingredients can be prepped and stored in the fridge for 3-4 days.
