In a large bowl, combine the coconut manna, coconut oil, sweetener, vanilla, and water. Add in remaining crust ingredients and knead by hand until a sticky dough forms. Form it into a ball. Note: it will be falling apart a little, and that's ok. Just form into a ball as best as you can and you're good to go :)
Line a rolling out surface with some parchment paper the size of your cookie sheet. Place the dough ball on the parchment paper. Cover with a second same-sized piece of parchment paper on top. Carefully roll out the dough to a rectangle roughly the size of the cookie sheet surface, and to a ¼" thickness. Carefully transfer the rolled out dough (with the parchment paper) onto the cookie sheet. Peel off the top layer of parchment and discard. Use your fingers to patch up any tears.
Line the dough surface with the sliced pear, making a pattern of your choice (I just did neat overlapping rows or pear), BUT be sure to leave an uncovered 2" edge of dough all around (this will be the part you'll be folding over later).
Drizzle sweetener over the pear slices, sprinkle with cinnamon and almond slices (or another topping).
This is the part that needs special maneuvering :) . To fold over the dough without breaking it, you'll need to work with one edge at a time. Lift up the parchment paper edges and fold the dough over the pears. Press it down gently and then peel off the parchment paper. Repeat for the next edge. Seal the corner with your fingers. Repeat until all the edges are folded over and a frame is formed. Make sure all the edges are sealed and feel free to touch up any cracks or tears.
Combine all the crust wash ingredients in a small bowl. Use a pastry brush to brush the wash over the crust. Place the entire tray into the fridge and refrigerate for 20 minutes. In the meantime, pre-heat the oven to 375F.
Bake in a pre-heated oven for 22 minutes, or until the crust is golden brown. Remove from oven and allow to cool on a cooling rack for at least 10 minutes. Serve warm or chilled, with a side of ice cream or some sweet yogurt. Refrigerate any leftovers (they make a wonderful breakfast!).
