Laydown a 2-foot long strip of plastic wrap on your kitchen countertop. Place chicken breasts on the plastic, leaving a 2-inch space between each breast. Cover the breasts with another strip of plastic wrap, so the meat is sandwiched between two layers of plastic wrap.
Use a mallet to pound the breasts until they are a little less than ¼ inch thick but be careful not to rip the chicken. Season breasts with salt and pepper.
Setup three wide, shallow bowls and a large plate on your countertop. In your first bowl, place the potato starch. In your second bowl, beat the eggs. In your third bowl, stir together the matzo meal, za’taar, paprika, coriander and1 tsp salt and pepper until well mixed. Leave an empty plate nearby where you will place your coated chicken breasts.
Pour oil into a skillet until it’s deep enough for frying (about 1 inch). Heat the oil slowly over medium until it reaches 375 degrees. While oil is heating, dip each breast one by one into your breading bowls, coating them on both sides with each ingredient. Starting with potato starch, then the egg and then the seasoned matzo meal.
When the oil is hot, fry the coated breasts 2 at a time until they are golden brown on both sides, about 3-4 minutes per side.
After frying, set the schnitzels on a wire rack or a paper towel to drain off excess oil. Sprinkle the schnitzels with additional salt to taste.
To assemble as seen in the picture, place a large dollop of sunchoke puree towards the center/edge of the plate, and on top of that place a schnitzel. Top the schnitzel with the horseradish chermoula and add some of your favorite roasted veggies (I opted for sweet carrots).
