Melissa is into the weekly batch cooking process and writes about it in both books as well as her blog.
Melissa uses this process so that she can decide on the spur of the moment what to have and prepare very quickly.
She divides it into two sets of food kinds: Recipes and Piles (Hot Plates).
More on Hot Plates here. They're essentially throwing together meat, veggies, spices and sauce very quickly. She just has a series of prepared "piles" of ingredients you can quickly throw together in a stir fry.
Meal planning makes things easier for you, makes cooking less of a chore, saves on waste and saves money!
