Make dinner super simple:
soup and grilled cheese sandwiches
pancakes (I LOVE Batter Blaster for quick pancakes)
I freeze leftover pizza from Dominos and toss the slices in the oven at 350 for about 8 minutes
Frozen burritos (put them in the oven and do other stuff while they are cooking, better than microwave)
frozen ravioli or tortellini, cooks in about three minutes, toss garlic bread in the oven when you put the water on to boil, put sauce on the hot pasta and you don't have to heat the sauce.
scrambled eggs with cheese and bagels.
Most of these ideas are easy on the clean up too.
I also get all DD's clothes picked out for the week and ironed on the weekend. I hang them in my closet with socks, tights, etc on the shelf. Then they are easy to put out the night before. Takes one minute.
Can you prep lunch stuff? Prebag chips, grapes, cookies so all you have to do is make the sandwiches and put it in the lunchbox? Or some days, instead of sandwiches, send cheese and crackers. You could have the cheese already cut up and the crackers bagged.
I know all this prep steals time from the weekend, but such are our lives.
What are the kids doing during the drive? Can they take lapdesks and do some homework in the car? Or you say you do reading with them, is this them reading to you? Can that be done in the car?
