Food for fussy 4 year old

[moresproutspleasemum]

What bland, child friendly meals can I try on my 4 year old? Cheese or tomato based ones or any others? They are incredibly fussy...

Ours will only eat cheese. Wraps with cheese and mayo, Mac 'n cheese, sausages, chips occasionally, pancakes with or without cheese, but he does like fruit. I just think there's no point trying to introduce variety into his diet because he doesn't want variety.
