To make gluten free breadcrumbs, process Udi’s Gluten Free bread into your food processor. Preheat oven to 300 degrees. Place crumbs on a parchment lined cookie sheet. Bake for 5 minutes. Turn oven off and allow to sit in the oven for another 45 minutes. If desired, process in your food processor again for a finer breadcrumb.
Slice goat cheese and form into rounds. In a shallow bowl combine breadcrumbs, onion powder, garlic powder salt and pepper. In another bowl whisk egg. Dip the cheese rounds in egg and then toss in breadcrumbs to cover. Transfer to a parchment lined plate. (May be done ahead of time. Refrigerate until ready to cook.)
Heat just enough avocado oil to cover your pan to medium high heat. Add goat cheese and cook until browned, 1-2 minutes per side. Removed from heat and place on a paper towel-lined plate.
Meanwhile, make the dressing by combining balsamic vinegar, red onion, maple syrup, dijon mustard, garlic and sea salt in a blender. Process until smooth and then add oil in a steady stream.
In a large bowl toss arugula, grapes, onion and walnuts with the desired amount of dressing. Transfer to serving plated and top with warm goat cheese rounds.
