When you have a messy space in your fridge and not much time for cooking, you can always store your food in different sizes jars. Take out all the food that you have in your refrigerator- vegetables, meat, eggs, fruits, greens. Cut the vegetables in small to medium sizes cubes and roast them all together in a big aluminum pan. Season them according to your taste! In the same manner, roast the meat and/or the fish, in the oven, allowing them the necessary time to be done. Boil pasta and hard cook the eggs. Meanwhile, wash your mason jars and the lids and let them dry! When finished cooking, set everything on wide plates and let them chill. Start filling your jars, making sure that you place the heavy items on the bottom and the light ones on top! Cover the jars with lids and store them in the refrigerator for several days!
