I doubt I could make it on $4 a day for food and I have no desire to try. Today I spent over $30 just buying stuff to fix for dinner. Granted, I didn't use all of what I purchased and what's left can be used for another meal, plus that $32 included a $12 bottle of wine. The dinner was for enough for my wife and myself for those who are keeping a tally.
I fixed prawns plus pasta with Alfredo sauce, sautéed mushrooms, capers and fresh grated parmesan cheese. For a vegetable, I sliced a zucchini, grilled it and served it with sundried tomatoes on top.
I have about a half pound of prawns left, some sliced mushrooms, one zucchini, 3/4 a jar of sundried tomatoes and a 1/2 jar of Alfredo sauce. I am presently drinking the last glass of Chardonnay.
