Prepare the crust, combine Gluten-Free All-Purpose Flour (I used Krusteaz brand) in a bowl, add almond flour, ground flaxseeds, curry powder, baking powder, salt in a large bowl and mix well.
Cut in vegan butter (I used Earth Balance brand) in the flour, using a pastry cutter or your fingers until the dough is crumbly and looks like bread crumbs. Add cold water and mix to form a dough ball, the dough will be much wetter than you are used to but don't be alarm. Cover bowl and transfer to refrigerator for 30 minutes.
Preheat oven to 400 degrees F. Line a baking sheet with parchment paper and lightly spray or grease with oil. Set aside.
Remove the bowl from the refrigerator. Divide the dough into eight or nine pieces. Using an extra sheet of parchment paper, roll out each piece of dough into a 4-inch circle about 1/8-inch thick. Add 1 heaping tablespoon or more of cooked callaloo in the center of the dough.
Fold half the dough over the filling to make a half-moon shape, then press the edges; the edges should easily stick together. Using the tines of a fork, press the edges to seal. I'd like you to please repeat until all the dough balls are filled.
Transfer patties onto the prepared baking sheet, bake for 25- 30 minutes or until golden brown.
