Heat diced apples, lemon juice, light-brown sugar, cinnamon and nutmeg in a medium saucepan over medium high heat. Bring mixture to a boil, stirring frequently, then reduce heat slightly and allow to cook until apples are tender. Then add butter and stir until melted.
In a small bowl whisk together cornstarch and water until well combine, then while stirring, pour cornstarch mixture over apple mixture and stir until thickened (it should thickena quickly).
Serve warm covered with optional sweetened whipped cream. ice cream or caramel sauce along with cinnamon sugar tortilla chips for dipping (alternately you can layer the chips followed by ice cream and finish with apple pie mixture rather than dipping).
Cinnamon Sugar Tortilla Chips
In a small bowl, whisk together sugar and cinnamon, set aside. Line a baking sheet or several plates with paper towels, set aside.
Fill a large saucepan or cast iron skillet with about an inch of oil and heat over stove-top set at medium to medium-high heat until oil reaches 350 degrees on a deep-frying thermometer.
Drop tortilla wedges, about 8 at a time (they should fit in a single layer) in hot oil and cook until bottoms are golden then using metal tongs, flip and cook opposite side and cook until golden. Transfer fried chips to paper towel lined baking sheet then immediately and generously sprinkle with cinnamon sugar mixture (or the sugar won't stick). Best served day prepared.
*I'd recommend dicing them into very small pieces about 1/4 - 1/2-inch since this is for dipping, it will also help them soften faster.
