Single person, feeding themselves, little money

So someone I know is in dire straights. They want to know what to do for food as a single person with little money. Here's my initial response:
      Roasting a whole chicken costs about $5. That's four huge portions. Good basmati rice, about $6 for a five pound bag--enough to feed 40 people. So roast a whole chicken, cook rice, about 17th of the bag. Both will last for several days in the fridge. Mangos are going for $.50 each right now, so you can add a mango a day for half-a-buck. Lettuce, good romaine, is going for $1 a head and a head will last 3-4 days. Broccoli is about $1.60 a head and that will last 5 days for a single person. So for $8.50 you've got a main meal for 4-5 days. Add a quart of oil for a month, which comes to $.65 per week. Add salt and pepper: $.10 a week. Breakfast: Three eggs with toast: Eggs, free range, are $3.00 a dozen or less. Bread by the loaf, good quality, is $3. a loaf. Both of those are good for several days. Add organic yogurt, 6 ounces for lunch, at $4 a quart, and you're up to about $10 for four-five days. Large naval oranges are currently $.50 each. Add one. That's breakfast, lunch, dinner. Meat, eggs, fruit, veggies, yoghurt, salad. Dressing might bring you up to $10.50 for four days, or $75 a month. I can give you recipes that will make all of that fantastic, give you variation with beans and veggies and so forth. Money left over for inexpensive ice cream and a few apples a couple of times a week and you still come in at less than $20 a week. Substitute lentils for meat and wow! You're on your way.
