I plan our meals twice a month always around the 1st and the 15th as that is when our local grocer has the best sales. I plan breakfast, lunch, dinner, and snacks for 15-20 days- not all of these are things I cook but by having a menu, I know I most likely wont have to run to the store or rely on fast food because we dont have something to eat. On days I know there is no time for cooking, I plan crockpot meals, many of which I can make the night before and just put in the crockpot in the morning. I also prepare as much as possible when I bring the food home. Ground beef can be cooked and sauce can be added and frozen, chicken can be put in freezer bags in the marinade you plan to use and just leave it out to thaw in your fridge while you are at work and pop it in the oven when you get home. I also have a great frozen potato casserole recipe that I make and freeze that can go well with chicken. Meatballs are another staple in our house. I make and freeze my own, then add some sauce and pasta and you have a meal in just a few minutes. Tacos are another quick meal, even quicker when you have made the meat ahead. I also freeze casseroles, lasagna, etc. By having meals already mostly prepared I have more time in the evenings for everything else. Of course, the two days a month I cook, I spend several hours prepping everything but its well worth it in the long run.
