These kind of assignments used to be what we did in home ec class.
Start with what is easy. For me, that's figuring out supper. Then, figure out the rest. I used to go to a blog where she had a set lunch menu for every day of the week. If they had leftovers, they ate those, but if not, they had the set menu. It was fairly easy stuff, like egg salad one day, corn soup the next, rice and bean burritos. Whatever your family likes.
When I was pregnant, I was obsessed (obsessed!
) with getting 5 fruits and veggies every single day. Now, I do well most days, but I was obsessed. So, I started adding them in as snacks. I think you can round out alot of corners with snacks.
Oh, and at my house, anything will get eaten (by my babe and my dh) if it has salsa. So, that's how I hide lots of good stuff. Tacos with veggies, burritos, quesadillas with veggies, gorditas, really anything. You can put almost any veggie in there, and it's good.
