I'd recommend sticking with ramen. There's zero chance that fruit is cheaper anywhere on a cost per calorie basis, ramen is easier to find everywhere, ramen is pretty tasty and you can take more calories of ramen before you want to throw up, you can take more calories of ramen before you have diarrhea, ramen stores compactly and easily, ramen doesn't go bad, and the health benefits of fruit and vegetables are greatly exaggerated ( partly by some folks whose interest in promoting them has nothing to do with their purported health benefits). I, for one, never get sick, work out all the time, am slim and stronger than 99% of the population, have good blood pressure and cholesterol, and, to cut costs, a significant portion of my diet is ramen.
I was merely pointing out that if you have limited funds and running a startup, ramen and exercise is not a bad trade-off considering the costs of fruits/veggies are usually higher.
Standard Ramen pretty much has no nutritional value. Add some veggies (first boil finely chopped carrots & celery, add frozen corn, broccoli, peas) then put in the ramen mix.
