Go to Kraftsfoods.com or Campbells.com both sites are incredible offering up very healthy and easy meals. Most of the ingredients you may have on hand.
You don't have to be a good cook to follow a recipe!! :)
You will have to go to the store more frequently though, introducing salads, fresh veggies and fresh fruits into your meals and snacks is essential to turning a new leaf. Produce has to be bought every five days for it to be fresh.
You can do so many things, like easy breezy quesidillas, get a rotesserie chicken already cooked at the store too, I do this as I like to cook but not in the summer! You can do so much that is easy but need to go to the store and make sure you are stocked up on easy options that are fast. Keep spaghetti sauce and noodles stocked up, neither goes bad fast and easy to keep on hand.
On Sundays, take two hours, prepare three or four meals, put two in the freezer, use the first two and on the second day put out the ones in the freezer to thaw in the fridge.
I write out my meal plans for the week ahead on Saturday, get coupons and shop on Sunday and then have it one hand, know ahead of time what I am cooking too. Good luck, you will do great! I even get frozen California Pizza Kitchen Pizzas as Friday is pizza night. I add a salad or cut up fresh veggies and in 10 minutes you have a meal.
