Heat a few tablespoons of oil at a time, as needed, in a skillet over medium high heat. Working with just a few pieces of fish at a time so as not to over-crowd the pan, dip fish in egg, then almond flour. Cook fish sticks for a few minutes on each side, until well browned, flipping fish to each side as needed to cook through. When all sides are browned, set fish sticks on a plate lined with a paper towed to drain. Allow to cool completely. Divide and place into indicated number of freezer safe containers with wax paper between layers, cover and freeze.
