Step 1Heat the oven to 350 degrees. Lightly grease two baking sheets. Combine the seeds in a shallow bowl or on a plate.
Step 2Whisk together the egg, 2 tablespoons of water, salt and pepper to make an egg wash. Brush the egg wash onto the tortillas, then dredge each tortilla in the seed mixture to coat.
Step 3Place the seed-coated tortillas onto the baking sheets and with a pizza cutter, using an "M"-shaped motion, cut each tortilla into long triangular wedges. Bake for 10 minutes, until crispy and lightly golden.
