Stir fry: cut up some chicken and cook in a pan, add one bag brocoli slaw and sautee until tender. Mix together hoisin sauce and soy sauce in a 3:1 ratio and toss in some sesame oil and coat the stir fry mix. Serve over rice.
Switch up pasta: add pesto, white beans and baby spinach. Or diced tomatoes tossed with garlic, olive oil and parsley. Also, you can turn lots of different pastas into baked pastas - make the night before and just stick in a greased glass dish.
Tilapia cooks very quickly if you pan cook it. My family likes fish tacos - I just cook up some tilapia, put out some tortillas and some rice and beans or corn.
Grill for as long as you can - burgers, hotdogs, chicken, etc.
Pizza potatoes - stick baking potatoes in the oven right when you get home, right when they're done, take them out, top with a little tomato sauce and mozzerella cheese. (You can also do this with frozen french fries or tater tots, but obviously less healthy).
Eggs cook up really fast, and can be served with frozen hash browns, fruit salad or cooked veggies, baked sausage.
"fancify" sandwiches - grilled ham, apple and cheddar is really yummy. Same thing with turkey, spinach and boursin (or dill havarti). You can either make side salads the night before or buy them.
Finally, if you do want to go the crock pot route in the winter, you can prep everything the night before and put it in the pot, cover it and put it in the fridge. Then just take it out in the morning, add whatever liquid the recipe calls for and turn it on. I do this a lot.
Good luck going back to work!
