Cut hearts of palm lengthwise into thin strips and cut strips into ½ inch lengths. Place these in a large mixing bowl. Chop artichoke hearts into very small pieces and add these to the mixing bowl. Mash chickpeas and capers with a potato masher or in a food processor so that some peices remain, and add these to the mixing bowl with the hearts of palm and artichoke hearts.
Add all remaining ingredients to the mixing bowl with the exception of the arrowroot starch, plant-based mylk and apple cider vinegar. Stir to combine and form into patties using a one-third measuring cup. Place on a baking sheet and into the freezer for 20 minutes to firm up.
Place the arrowroot starch in a small flat dish. Add the cider vinegar to the plant-based mylk and stir. It will thicken to a buttermilk like consistency. Place this in a second flat dish. Combine all breading ingredients and stir until oil is evenly incorporated and place this in a third flat dish.
Remove patties from the freezer and, using one hand, coat each in arrowroot starch and dip in the 'buttermilk' mixture. Transfer the coated patties to the breadcrumb mixture. Using a spoon with your clean hand, cover the top of the patty with more bread crumbs and press them in gently with the back of the spoon. Using your clean hand, turn the pattie over and press the crumb mixture into the patty until it is evenly coated. Transfer to a parchment line baking sheet.
