Hi! There are many things you can make, especially if it is for only one person. I am not sure what the exchange rate is right now, but for $40 American dollars you can eat healthy for a week.
1.Pasta with tomato sauce or a little olive oil and sauteed zucchini sprinkled w/ Parmesan cheese.
2.Grilled cheese( I use wheat bread and low fat cheese) with tomato soup
3. Hummus sandwich -any bread with cucumber, peppers, etc.
4.Boneless chicken breast w/ brown rice($1 a box) and a frozen broccoli(tastes just as good as fresh, especially until it is in season)
5. PB sandwich
6. Buy fresh fruit in season and only what you will need for the week.
7.Yogurt (sometimes I eat this with a sandwich rather than fruit bc it is cheaper)
8. homemade pizza-sauce, lowfat mozzarella cheese, Pilllsbury dough(it is lowfat) and topped with a vegetable
Also, I eat lots of leftovers, so you would have enough for lunch or dinner the next day.
