Saute up 1/2 chopped onion and 1 cup grated carrots. Put half of this mixture aside, and the rest in a blender with:
1 tbsp flax meal soaked with 1 tbsp water for 5 min
2 tbsp sesame seeds
1 tbsp cornstarch
1 tbsp cumin
zest of 1 lemon
1/2 cup bread crumbs
1/2 cup water
blend until pretty much uniform, and then add water/bread crumbs as needed.
Stir in remaining chopped veggies, and form into patties. Bake at 350 for 20-30 minutes, until cooked through.
Serve on hamburger buns, with avocado, arugula, and red onion slices.
