Kirpa karo Amritvela jee,
please share recipes.Keeping bibek in university doesn't have to be too hard. My favourite thing to have at school is sabjee wrapped in parshada. Simple homemade sandwhiches are very good too. My advice is to make paneer sabjee over the weekends because it's so simple and easy, and you can save the paNee/whey to make
bread (click for recipe) which will last you the whole week. Then you can make sandwhiches filled with paneer sabjee to bring to school. It's
delicious. You will have enough panee/whey left over to make bread the week after as well, so you won't have to make paneer again, and you can switch to toasted tomato-salad sandwhiches which are
so good. 
Or if you don't want to make bread, simply make parshadey in the morning before going to school, or praunthey.
For things that you can eat while you're at home, many things require limited effort. Multi-grain dalian and khicheree are good hearty breakfasts or dinners, and if you don't mind people making fun of you, you can make them everyday. I personally don't get tired of them.
There is also a food which I think is the perfect bibeki solution to cooking problems, but no one uses it - quinuoa! Quinuoa is a type of grain from South America. It comes in red and white, you should first try white quinuoa. There are two ways to cook it. You can either boil a bata of water, put the washed quinuoa in, cover with a lid, and then turn the chulla off. Then you just leave it for a while until the water all gets soaked up and the quinuoa gets fluffy. You can also throw some cut up vegetables in so they get steamed on their own. OR you can simply boil it until it's done. You can add stir-fried vegetables, daal, pre-made sabjee, or just raw veggies or fruits and have it like a salad - you can add anything to it.
Another very easy thing to make at home is pasta. You simply get sooji (semolina flour) and gun it into an atta the way you would do for parshadey.... just need a bit of water. Then use a belna to flatten it as much as possible. Then cut it into thin strips (an easy way to do this is to roll it up first). Then all you have to do is boil these in water. In another batta you should prepare sauce, or stir-fried vegetables, or whatever you like.
Here is a recipe you can try to keep as a snack or breakfast to keep yourself from getting hungry throughout the day. It won't go bad so you can make alot at once and store it. Reduce the sugar and milk and replace with mashed banana. It will become like little cookie-cakes. Also add nuts, raisins, cinnamon, flaxseed powder, etc as you see fit, to give it more nutritional value.

Make salads as meals, Salads have no limits! Try experimenting with different recipes. There are loads of recipes out on the internet, youtube, and personal blogs. If one puts effort and plan things out right ahead of time in keeping full pehraa on their bibek, it will be very easy to keep, but if not then it can be hard.
