1yr old only eats cheerios and cheese?

Anyone have a little one around the age of 1 yr who will only eat select finger foods? My little one will only eat cheerios and cheese chunks on his own. One meal a day he will let us feed him and we'll try and get a meat and veggie down through the Gerber 3rds. He usually doesn't want us to feed him though. Is this normal for this age? I worry of course he's not get enough nutrients through meat and veggies. He drinks his formula pretty good but not too much. He puts a lot of finger foods in his mouth- chews them up for awhile and spits them out. Odd.
