No doubt you've experienced this annoyance before in one variation or another. Tacos sound delicious, but the shells on the counter require meat and toppings in order to be appetizing. The idea of spaghetti is mouth-watering, but not without the noodles that remain on the grocery shelf where they were forgotten. The vast majority of mealtime predicaments can be prevented with a little planning. Before heading to the grocery store, simply sit down and make an old-fashioned list. Plan a menu for the entire week with your family's input, making sure to include all the basic elements: main course, vegetables, starches and side dishes. This planning will add a few extra minutes on the front end, but it will save tons of wasted time hitting up the grocery store on the way home from work. It will also keep you from resorting to taco shells stuffed with spaghetti sauce.
