Do I need an oven? Vegetarian Meal Plan

I am considering buying the Vegetarian Meal Plan, The thing is I live in an student dorm with a tiny kitchen that only has a stove (no oven, microwave....). I would like to know roughly what percentage of the recipes included in the book require a full equipped kitchen. Also I would like to know the average preparation time of the recipes, because as a PhD student the cooking time that I can spare is unfortunately very reduced :/

Would you advice me to get it anyways?
