In a large bowl: chopped onion, 1lb of ground turkey, 3/4 cup Italian bread crumbs, an egg, garlic powder, salt and pepper.  Squish with hands, let little ones help, they love it.  Spray loaf pan with non-stick, press the meat mixture in pan, cook at 350 degrees for 40 minutes.  Pull out, put squiggle of katsup, put back in for desired crispy edges.  Pull out, heat green beans, slice meat cake.  Good stuff.
