Preheat the oven to 350°.

Butter a baking dish. Cut each apple into 8 wedges and add them to a bowl of ice water with lemon juice. Separate the crescent roll dough into triangles. Remove the apples from water and pat dry with paper towels. Roll each apple wedge in the dough starting at the smallest end. Put all of the triangles into the baking dish.

In a small bowl mix the sugar, ground cinnamon, and ground nutmeg until well combined. Sprinkle over the apple triangles, generously covering all portions. Cut the butter into small pieces and scatter over the baking dish, evenly distributing it around the dumplings. Pour the lemon lime soda over the dumplings. Bake until the dumplings are golden brown, about 40 to 50 minutes. Remove from the oven and arrange on a serving platter. Serve warm with a side of whipped cream or vanilla ice cream.
