Query: Norpro Meat Grinder

I purchased this Norpro grinder based on the feedbacks of others who bought it. My first project was green tomato, sweet pepper, and onion relish. The tomatoes wouldn't grind at all nor would the onions. And the pepper just kind of mashed up instead of grinding.. definitely NOT the grinder I needed to be using. All parts except the blade are plastic including the spiral feeding device. At most I believe this would grind COOKED meat not raw, and definitely not uncooked vegies.
