My system is to have a variety of meals that cost about $5 or less and we eat those most nights. Twice a week, on Wednesday and Sunday, I prepare a meal that is more in the $5-10 range. Those dinners always have a nice dessert too like cake/cookies. Sunday morning also has a nice breakfast which I don't plan but always happens. One of my family's favorites is copycat Cinnabons. LO is leftovers. I often add salad to a meal even when it isn't listed. I like to see what greens and veggies I have on hand or can pick up cheap to use. I make so much from scratch, no box mixes, kits or cans of this and that. I even make maple syrup from scratch. I keep a well stocked pantry of staples to do this. I always have a good supply of oil, butter, brown sugar, sugar, flour, wheat flour, oats, eggs, milk, baking powder and bulk yeast. I never plan shopping trips and menus around what I "feel" like eating. I pick up low priced ingredients and then use my freezer and pantry contents to plan meals. I use less of many ingredients in my recipes than called for, mainly oils(replace some with fruit puree, fat-free milk or water) and sugar(no replacement necessary), even eggs(replace with water or milk). It may be only $.10 savings each recipe but with how many things I make, it adds up to big savings over time and it's better for us. I save the heels of bread in the freezer to make stuffing and bread crumbs. I save the ends of vegetables in the freezer to roast and make vegetable broth. I save the cores of apples(not bitten apples, I cut off the apple flesh for the kids)in the freezer to cook down and process for applesauce. I learned to cook in my own family of 7, 4 of whom were young men/grown men so I got used to preparing a lot which works out for leftovers in my smaller family. We eat Flexitarian. Breakfasts are homemade wheat waffles/pancake/quick breads/muffins. Lunches are leftovers, natural peanut butter and jelly sandwiches, quesadillas, hot dogs, nuggets, eggs and veg. Snacks are air-popped corn, fruit and veg, plain bulk yogurt or cottage cheese with any desired toppings from the fridge, and anything from the standard breakfast or lunch menu. I have a huge freezer(costs $4 a month to run) to stock up on sale meat, cheese, milk, fruit and veg. We don't drink our calories. I do buy Coke a few times a year and we all split two cans on Friday pizza night. I do buy coffee beans and tea bags. We use a French press for coffee. Hubby makes his regular coffee first and transfers it to a thermal pitcher(thrift store $.25). Then I add a scoop of decaf grounds to his grounds and fill the press again. I like my coffee light. Not weak, just light so this works great for us to save $5 a month on coffee.
The Complete Tightwad Gazette, a good basic cookbook like the Better Homes and Garden red & white book and user reviewed recipe sites like Allrecipes help me to stay interested and inspired.
