Laura was asking about frugal meals. For breakfast we eat a lot of egg variations, because eggs are still the cheapest thing we can buy, really. Or get for free from our ducks.
Right now I'm on a baked omelet kick, where I just spray a mini-meatloaf tin and add two beaten eggs, 3 tbsp of vegetables, 1 to 3 tbsp of cheese and 2 tbsp of meat. I use up a lot of leftover veg this way. You can make them in large size muffin tins (not cupcake size) if you are making multiples.
Bake at 350 degrees F for 20 to 30 minutes. It really depends on your oven for the time. In my Nuwave it takes 20 minutes and in my gas oven it takes 30 minutes. I imagine an electric oven is somewhere in between. Stick a toothpick in the center and check that it comes out clean and that is when it is done.
My favorite variations:
2 eggs, 3 tbsp pico de gallo, 2 tbsp sausage, 1 tbsp sharp cheddar, salt and pepper
2 eggs, 3 tbsp chopped broccoli and cauliflower, 2 tbsp diced ham, 1 tbsp sharp cheddar, salt, and pepper
2 eggs, 1 tbsp chopped tomato, 1 tbsp diced green bell pepper, 1 tbsp diced onion, 2 tbsp diced ham, 1 tsp Italian seasoning, salt, and pepper
2 eggs, 1 diced green onion, 2 tbsp leftover or canned salmon or tuna, 2 tbsp Parmesan cheese, salt, and pepper
2 eggs, 3 tbsp leftover taco meat, 2 tbsp Mexi-blend cheese
2 eggs, 2 tbsp ground beef seasoned with garlic powder, onion powder, salt, and pepper, 1 tbsp diced Anaheim chili pepper, 1 tbsp diced red bell pepper, 1 tbsp diced red onion, salt and pepper
To make this easier on me, I will dice up a bunch of ham or cook a pound of sausage or ground beef and then flash freeze them flat on a cookie sheet for a couple of hours so they don't stick together, before bagging them up and leaving them in the freezer. That way I can easily measure out as much as I need the night before and it will be thawed by morning. I also have my containers of chopped veggies done up, so I can just mix and match in the morning. I am watching my carbs, so this is basically what I always eat, sometimes with additional veggies. For the rest of the family I have other options.
Another cheap breakfast we do is breakfast burritos. It is rather simple to do up a huge batch. It requires 24 eggs and 2 pounds of sausage. Brown the sausage, beat the eggs (I use my stand mixer because this is a lot of eggs), and pour the eggs over the sausage. Stir until done. If you don't have a large enough skillet for this, cut the recipe in half and do two batches.
Take a tortilla, spoon some filling in, add the cheese of your choice and roll once, fold one end up, finish the roll, and then wrap in aluminum foil. Freeze in gallon size ziplocs. This recipe will fill 4 bags. We keep one in the fridge and the rest in the freezer. When we run out we take another bag out the night before. My husband likes to dip his in picante sauce or salsa. I did this one for my youtube channel so if you'd like to watch it done here it is:
Scrambled egg sandwiches are another. You simply scramble your egg, butter a slice of bread, spoon the egg into it and fold the bread in half. It is simple, but amazingly good (even on cheap, ordinary bread).
Pancakes and waffles are something that can be made ahead and frozen individually so they don't stick together and then bagged up for the freezer. They can be warmed up from frozen or you can just take them out the night before and then warm them up. You can use mix, but they are simple and cheaper to make from scratch. Add some hard-boiled eggs and you have your protein as well. French toast also lends itself to make ahead and freeze and is very simple to large batch cook.
Breakfast is probably the easiest meal to save money on if you don't mind some repetition. I think lunches and dinners are more of a challenge, but I will go through my recipe binder and see what I come up with. Since we buy so much in bulk off of farms and raise some of our food ourselves, it is harder for me to figure what other people's costs are. But I do have some that I think will fit the bill.
