Well, if it was that recent, your first priority is to eat something that will not upset your stomach after the drugs you've been given.
Beyond that, vegetables are never a bad plan. It kinda depends on what surgery it was and what your overall state of health is. You had your sesamoid bones removed, right? In that case, just focus on fresh fruits and vegetables to keep your immune system up and make sure you heal properly (Vitamin A and C are vital for healing). Some meats and grains will keep you full and supply protein and iron. Just generally good food.
One issue with foot injuries is, what kind of help do you have? Are you providing your own meals? If so, convenience is going to be a huge factor. I'm on crutches right now myself, and my latest triumph of laziness is eating dry cereal out of the box with a cup of milk for breakfast, because it's easier to carry a cup than a bowl!
If, like many patients, you have family but they aren't home in the daytime, you may want to ask someone to prepare you some food and put it in the fridge, or at least make sure you have sandwich fixings on hand. Nutritious TV dinners aren't as good as home cooking, but they are far better than trying to make a meal out of chips and crackers. I'm rather fond of anything made by Annie's.
If you are going to be laid up for a while, avoid junk food so you don't gain weight. (While on drugs and in pain, many people actually lose weight. It's the next stage of recovery, feeling kinda ok but still not able, where you have to look out for weight gain.)
