here are two meals i made up today, total prep time was about 10 minutes for both meals combined.
Lunch:
some variety of sweet potato, sprinkled with cinnamon and butter(heavenly). some smoked salmon i had in my fridge from the supermarket. a bit of a strange combination, but hey, it fit the bill.
total cost of meal - 1.6euro for salmon, .4 euro for sweet potato = ~2 euro
Dinner:
Salad - Sardines, half an avocado, mixed lettuce, olive oil, oysters. Water to drink.
total cost - 1.9 euro sardines, .5 euro avocado, .3 euro lettuce, oysters 1.2 euro = 3.9euro
