Quoting Joe&Bria's ℳomma:" Looking for good lunch ideas to pack for DS when he starts school! TIA!!"
You should check with his school. There are restrictions at my DDs school due to allergies (no nut products at all, not just peanuts, no shellfish). It made me have to change some of what I planned on packing for her.
But on my DDs list of options are:
Meat and cheese sandwiches
Tuna salad sandwiches
Hot dogs (with ketchup to dip it in)
Salads (my DD loves salad with shredded meat on top and a little bit of ranch to pour on top)
