Yea I'm not sure how someone can claim "$5 for a meal for one" could possibly be cheaper than cooking unless you're deliberately cooking something expensive?
Now maybe I'm missing some cultural context for the price of produce in the US but for €5 per person here in Ireland I could make an absolute feast. Say I make a ragu for 4-5 people, here's what my shopping list might look like (checking prices on tesco.ie):
- Pasta 500g (€0.65)
- Ground pork 400g (€3.50)
- Bag of onions 1kg (€0.60)
- 4 bulbs of garlic (€0.80)
- Bag of carrots 500g (€0.60)
- Celery 450G (€0.79)
- Tinned Tomatos (€0.45)
So for €7.39 I could feed 4-5 people and have most of the onions, garlic and celery left over for another dish.
If I had the budget to get 5 people Taco Bell at €5 a head, I could cook that recipe twice over and have enough left over to buy a half-decent bottle of wine.
I know scale changes if you live on your own say, but that's when you save stuff for lunches, make smaller recipes etc. And I live in one of the highest cost-of-living countries in the EU - is the situation really so dire in much of the US as to be drastically different?
