I was thinking the same thing when I saw the $511 grocery bill
4 x Hungry Jacks small burger meals per day @ $7 each, works out to be $196 per week, no need for plates, knives, forks, detergent, fridge etc, and it only works out to $10220 per year, could mix it up with a few Domino's budget pizzas, chicken dinner or two from Red rooster all within budget, and it leaves $315 per week for living it up
