How do you define vegetable here? A whole lot of (dis)agreement below seems to hinge on that. The dictionary definition of vegetable (according to dictionary.com) is: > any plant whose fruit, seeds, roots, tubers, bulbs, stems, leaves, or flower parts are used as food Which would include grains, however you may be excluding those depending on if "heavily processed" modifies only the oil, or the grains as well. Of course culinarily in western traditions, grains and a lot of tubers are excluded from that, as are some fruits (others, culinarily speaking, are considered vegetables like squashes, tomatoes, and so on). Also, in your question, would olive oil count? Its literally the result of squishing olives.... does that count as heavily processed? Do you count potatoes? They are pretty calorie dense. Beans? Plenty of calories and lots of protein. What about seed foods - nuts and such? They are also calorie dense and have a lot of fats too. Point being - it's really unclear what limitations you're placing on it... peanuts, beans, (sweet) potatoes, squashes and fruits are commonly grown in home gardens, widely considered vegetables, and calorie dense enough to sustain a person fairly easily without non-stop eating.
