Use any kind of non-leafy vegetables (e.g. broccoli, kohlrabi, carrots, radishes, green beans, mushrooms). The proportion of each does not matter. If using organic vegetables, they do not need peeling.

For best results and to avoid crushing ingredients or getting the spirals tangled in the blade, the vegetables and fruit pieces should be at least 4 cm long and maximum 10-11 cm long. Keep this in mind when shopping and preparing your ingredients so as to choose and cut them accordingly.
