I decided to pay walmart's website a visit and see roughly how much food $50 will get you. Obviously prices vary by location, but not so significantly to undermine my point. Lou is, of course, a manchild that will never do any real cooking, so I'll stick mainly to easy to make foods like canned goods.

Pinto beans and black beans. I picked two kinds for variety, and because they're the same price. Five each at $0.92 comes out to $9.20 total. Technically, it's 3.5 servings per can, but I'll round up to 2 servings for ease, and because I know the fat fuck really wants to eat the whole can.

Two precooked rotisserie chickens. All the flavors are the same price, so I selected two kinds for variety. It's about 8 servings per, but I'll call it 4 because Lou is a fat fuck. They're 4.97 each, and our total becomes $19.14. No cooking required!

Four boxes of instant rice, $2.46 each. Once again, no cooking required. Eight servings per, but I'll assume it's 4 servings since Lou is fat. That comes out to $9.84 and brings our total up to $28.98.

A gallon of milk. Useful for cooking, useful for drinking. Sixteen servings per gallon. $2.32, bringing our total to $31.30.

5lbs of russet potatoes. Easy to throw in the microwave or boil in a pot. Very filling. No idea how many servings that is, but its a lot. $2.97, bringing our total to $34.27. Consider how many meals just the above can make. Not the most nutritious meals, but that was never something he cared about. Filling and enough to get a poor person through the day.

Six cans of canned, mixed vegetables. 3.5 servings per container, but once again I'll assume two. $5.76 for six cans, bringing our total up to $40.03.
This leaves just under $10 for whatever butter, spices, condiments, cheeses he might want to top all this.
While I'm not saying grocery prices are great right now, they're sure as fuck better than eating out. This isn't even the cheapest it gets, I just tried to make something a lazy fuck like Lou might be able to tolerate since they're all essentially "heat and eat". To get it delivered is $9.99, so assume $60 total for all of the above. This is enough food to feed him for over a week.
I know nobody that gives him money will ever read this, because Kiwi Farms is literally Hitler, but if they'd spend five minutes looking at his spending habits, they'd wise up.
