1 year old won’t eat much

Hi mommas my 1 year old doesn’t really eat much table food , he drinks milk & water . I give him snacks things he likes is carrots, apples, grapes, Cheetos , puffs, cereal, he doesn’t like meat or chicken he loves mashed potatoes and French fries. I don’t know what else to do I tried giving him certain foods I eat and he spits it out . Any advice ?
