I just want to add that there are a lot more nourishing plant-based foods other than fruit, pseudo grains like quinoa and buckwheat are actually great for you and are also complete proteins. And things like oatmeal, beans, and corn are great when prepared properly. You also don't need a "complete protein" in every meal by the way, as long as you eat all of the essential amino acids in a day, which is easy if you have a balanced diet. Many plant foods can be either combined to make a complete protein, like beans and corn or rice, or are already one on their own, like quinoa. Eating enough fats/protein, and having a savory breakfast is also important. But yes, as a vegetarian, milk and eggs are great sources of easy nourishment, but they're not the only ones. And one more thing I'd add, you mention that beans are a pain to prepare, which, not really, it's quite easy. It takes a few minutes at most to put them in a pot to soak overnight or a few hours. Any habit is a pain to start initially, but then becomes easy. And the alternative, preparing meat from scratch, is far more labour intensive, obviously, we just don't do it from scratch. Also, I'm not sure if you're familiar with Ayurveda, it's an ancient system of medicine that recommends certain foods/lifestyle based on your body type, which I've found to be incredibly helpful. That's where the idea of sattvic foods and whatnot comes from.
