Next, use a matrix to assure variety of meals. So,e people use a theme based matrix, some a protein based matrix, whatever works for you. It's important to have a plan, even though you might not always use the plan. Yesterday I went to Safeways to get a few things that were on sale. I foimd so,e I had t seen, and had coupons to make things better, and I found shrimp with yesterday's pull date at 1/2 off. We were supposed to have salmon for dinner, it wasn't much of a stretch to substitute shrimp. I was already 1/2 way there when I had to go to the imaging clinic. I don't travel ten miles to save .25. LOL.
I digress - meal plans - not nexessarily on order
- Sweet and sour chicken , rice, mandarin oranges
- Pizza
- Chicken tortilla soup
- Sausage and saurkraut , apples and bread
- Speghetti and meatballs , French bread
- Split pea soup , crescents
- Breakfast 4 dinner
Notes :   A batch of chicken breasts can be cooked at the same time for sweet and sour chicken and chicken tortilla soup.    I'm still working on dollar a pound chicken.    
Pizza is veggie 
Sausage was bought for a dollar.   Apples cut the sharpness of the saurkraut.    Bread sticks can be made from pizza dough easily.   Make dough. Let rise once ( 10 minutes.) flatten out in a baking sheet with sides,  dish with melted butter or oilive oil. Sprinkle with garlic powder and oak cheese.  Bake as pizza dough.  Slice into sticks with a pizza cutter.    
Speghetti and meatballs.  Meatballs are already cooked.  Speghetti sauce is as cheap as .58 and never more than a dollar on glass or .88 on cans.   Orontonsoegjetti was .75 with coupons.   
Tuna  casserole.     I have been weighing out the noodles, with only three of us eating them, I have been making a 8x8  pan of a casserole instead of the 9x13.   Less waste.    I got albacore tuna , wild caught for 1.25 at grocery outlet.    I make my own cream sauce mix, and cook whole carrots.   
Breakfast for dinner is a given.    Scrambelled eggs, fruit and some kind of starch: pancakes, waffles, English muffins ( cheapest at FM) or regular muffins,    Muffins can be made for less than a dollar.    It a good take and go breakfast too.    
Four dollar a day budgets allow for a dollar a plate for breakfast, lunch, and dinner, and a dollar for snacks and staples like oil, flour  etc.    
My breakfast consists of a bowl oatmeal made from a bulk oatmeal box from Costco and a banana.   I got a cog box of ancient grains cereal on a sale at grocery outlet o might swap out for some variety.   Less than .50 including the banana.   Bananas are cheapest at Costco.   Look formwhole hands, not singles put on the bag.   Most bags I have found are closer to 3.5 pounds,   If they add 1 banana they are going to be closer to the three pounds.   
Lunch is leftovers or a sandwich or soup,    I got chicken noodle for .45 and progresso  chinky for .75 
That will feed two of us with crackers or bread.
Having less expensive lunches frees up money for a stock. Stocking is the backbone of eating on the cheap. Good food cheap - not cheap food.
