In a medium bowl, combine potatoes, shallot (or onion), corn, peas, garlic, flour, panko, baking powder and spice blend. Toss well to combine.
In a small bowl, combine chia seeds with water. After one minute, they should begin to gel. Add them to the potato mixture at this point.
Using a large mixing spoon or rubber spatula, thoroughly incorporate chia seeds into potato mixture.
In a large sauté pan, add enough oil to cover the bottom of the pan. Heat oil over medium heat.
Using a 2-ounce scoop or ¼ cup measure, portion mixture into 12 patties.
Pack mixture tightly with your hands and gently place into hot oil.
Cook for 4 – 5 minutes per side.
Drain on paper towel – lined plate to absorb excess oil.
Serve warm with dipping sauce, if desired.
