My ds is 7 and he likes :
Sandwiches/rolls/wraps
Cut up chicken breast/ham chunks or whatever may be left from a bit of meat I've made for tea
Veg-Lidl's 'snack' cucumbers (just small extra crunchy cucumbers, regular size ones go too mushy he says) or carrot sticks, baby corn or halved cherry tomatoes, sliced celery etc
Fruit- a tangerine, strawberries with top cut off, pineapple chunks, an apple, sometimes raisins or the dried fruit & nut 'shot' packs which might have mini white choc or milk choc chunks
Yoghurt pouches (twist top only)
Mini packs of almonds or cashews
Home made flapjack
Mini pack of biscuits sometimes like mini party rings
Soreen lunch box loaves (apple/original/banana)
Pain au chocolat
Sometimes cocktail sausages or slices of pizza
He'd never eat a boiled egg or rice or pasta salads or have dips as he also is autistic and likes non messy/wet foods
Oh he does like a wee rice pudding pot sometimes though that's a recent development!
