Raquelita -
Of course it is your preference - but I could not live without one! Using one is just like using a Dutch oven and slow cooking in the oven for hours. A crockpot/slow cooker can be used to cook anything - appetizers, beverages, desserts, cakes, breads, casseroles, soups, stews, meats/poultry/game, etc., pasta dishes, sauces, sandwiches - you name it. I do use mine all year 'round (actually I have a 1-qt., two 3 1/2 qt. and a 6 qt.) and I love it during the summer months because I don't need to use the oven and the house stays cooler.
If you need any particular recipes for foods you enjoy - just ask - I have many for the crockpot and I am willing to share them with anyone who would like them!
But this is just my opinion -
