Crockpot, crockpot, crockpot!Set up your crockpot overnight when it's coolest and the electricity rates are low!
Check the various crockpot recipes threads (there's at least one active one in Meal Planning and one in Nutrition, as well as all the archived ones), and the Pantry Challenge threads for suggestions on how to turn various crockpot efforts into multiple meals. A great one is to do a chicken in a pot and eat that one night (chicken, potatoes, veges), then use the leftover chicken for burrito fillings, salad toppings, sandwiches, casseroles. . .Then you can throw the carcass back in the pot with water and veges and have soup the next morning!
I'm also a big fan of my microwave and toaster oven when it's hot. Cook baked potatoes in the microwave. Top w/ microwave heated chilli, shredded cheese, cold sour cream, chopped avocado, etc. Also, we do nachos in the microwave a lot. We'll do a big plate of chips with beans and cheese, then separate bowls of toppings. Everyone digs and dips as they please. Good for family meals! Cold pasta salads are nice, too. If you cook the pasta at night and assemble the salad then, the flavors blend while it sits in the fridge until the next day.
Here's a quickie that we did last night - cooked on the stove in our horrendously un-ventilated, super-hot kitchen in the 80+ degree heat and it didn't make me pour sweat, so I know it's a keeper!!
Spread two WW tortillas w/ pizza sauce
Sprinkle one with shredded mozarella
Top w/ whatever you like, but make sure if you use veges, they are cooked.
Lay cheesed tortilla in hot frying pan, lay other sauced tortilla on top (like a sandwich). Press down in pan. Cover and turn heat to med.
It will "puff" up a bit after a few minutes. Press down and check to see if bottom tortilla is browned. When it is, flip and cover again. Check after a few min to see if bottom tortilla is browned. When it is, remove, cool a bit, slice and eat!
Using a cover on the pan keeps the heat in, which keeps the kitchen cooler and cooks the food faster.
