I need some inspiration on what to offer my kids for lunch....

My boys have ASD and one is a white food eater, while the other has dairy intolerance but my DD is fine so I'm looking for ideas on what I can offer them for lunch everyday.

My OT and I have just worked out that I need to establish a good routine for our days to hopefully promote better sleeping patterns and behaviour as my boys don't cope to well with the 'go with the flow' method we currently use.

So I'm now working on setting up a daily roster of when they eat, play, sleep etc so thought if I'm going to that extreme then I might as well include meal options for the 'eat' section so that everyone knows what they will be eating at our set meals.

So hit me with some quick and easy lunch ideas that are more than vegemite sandwiches and crackers (which they currently live on).

I don't want to have to spend every lunch time cooking meals but would like to offer some variety if possible, although I may trial a lot and find that they won't eat it anyway...

I'm thinking we will have days where the options will be
Vegemite Sandwiches on Multigrain Bread (something they will eat)
Tuna or Salmon Patties
****tail Franks (something they will eat)
Ham, Cheese, Tomato toasties - or variations on that as they all won't eat everything
Pita Bread with Hommus and Carrot & Celery Sticks

Any other ideas on what would be a good lunch option - taking into account they will also have Breakfast, Morning Tea, Afternoon Tea and Dinner as part of the meal plan so lunch doesn't need to be huge.
