Re: School lunch ideas, on the CHEAP!
My kids would actually eat the same thing every day (and they often do)
When Kearnan went to school he ate
apple slices or grapes
yogurt in a tube (they sell reusable tubes on amazon that you can freeze so it keeps the lunch cold too)
whole grain crackers or whole wheat tortilla
He now also eats almonds and hard boiled eggs so if I sent him to school I might send those but I would ask before sending almonds as some schools that are peanut free don't allow other nuts.
He is also a huge fan of rice, he will eat it plain but he also loves home made sushi which you can make with just veggies in it for school lunches (avocado is quite good) or make rice balls with fried egg and veggie inside. Actually he likes cold omelets too.
