WOW! Seems like you need to come up with a few shortcuts. Here's a couple ideas about saving time cooking. 1- A slow cooker is actually very safe to leave on by itself. Invest in one and take a drive to your nearest bookstore for a slowcooker cookbook. All you do is throw the ingredients into the slowcooker, turn it on low, and go out the door. Dinner is ready when you get home from work. Their are thousands of recipes for slow cookers. 2- Casserole dishes. Make several different dishes on your day off, freeze them, then all you have to do is heat them back up when you get home from work. 3- There's a section in most grocery stores where you can get pre-cooked meals (I'm not talking about lean cuisine type either). My favorite contains beef tips. All you have to do is microwave them while bowtie noodles are heating on the stove in one pan and veggies are heating in another. 15 minutes, you have beeftip noodles and veggies on the side. That same section of the grocery store has several other quick 15 min meals as well as pre-made mashed potatoes. Check it out. 4- Chicken parmeson (sp?) along with spaghetti takes 20-30 minutes total and it's a fave in my family. Buy boneless breasts, grated cheese, a little extra spaghetti sauce and a box or two of Shake & Bake. The directions are on box.
A trick I learned is to do dishes while cooking. Most meals don't need you to do more than check on them so you can do other stuff while you work. Clean as you cook and it takes less time because your dishes aren't sitting there with food drying on them (which makes it harder to wash them and thus takes more time).
To shorten laundry time...hang hang hang! Hanging clothes actually takes MUCH less time than folding and putting away. I keep the plastic kids hangers than come with new clothes and use them for my daughter's clothes. This way, her outfits are already put together and I don't have to go looking for matching shirts. Buy large ziplock bags for those little kid socks. It keeps them all together and makes them easier to find and match up.
If you'd like some more quick recipes, let me know. I'll send you some of mine or find you some.
