Stir together onion, thyme, oats, garlic, yeast flakes, and seeds. Combine 3 c. hot water, liquid smoke, and soy sauce, then add to dry ingredients. Let stand for 30 min. to thicken. Using heaping 1/4 measuring cup, place onto well oiled cookie sheet and form into pattie. Bake 40 min. at 350 degrees, turn patties over and bake 20 min more.
These are so good, my son even takes them in his lunch to school.
