I know how it is to work in a restaurant. It's just easier to eat their food, even if it gets repetitive, and it's not very nutritious.
Given time, you'll find plenty of things that work for you, but I don't want you to starve in the meantime.
There are plenty of really quick foods you can make that are nutritious and delicious. It will require a bit of trial and error, and grocery shopping though. You have to do it, even if you are tired and working all the time. Find an hour or so to head to the grocery store, either before work or on a day off.
Here are a few ideas for you:
Instant oatmeal (I like the Nature's path brand) - then just throw in some milled flax seeds or chopped walnuts for good fats, and maybe 1/2 a banana sliced or a handful of berries.
You could also do the same with some granola and soymilk, or soygurt.
Amy's burrito's - the bean and rice ones are great for any meal, breakfast, lunch and dinner.
Lunch/ Dinner (which you could bring to work):
Any kind of wrap, pita or sandwich bread, filled with some veggies and protein.
hummus, tomato and avocado (and fake bacon if you so desire)
Veggie cream cheese (whatever brand you like), cucumbers, sprouts and tomatoes
Veggie deli meats + veggies
Mock tuna salad - here's an addictive recipe: https://www.veggieboards.com/boards/s...ock+tuna+salad
Or, for non sandwich ideas:
Some crackers, cut up veggies, dip (hummus, babaganoush, mushroom pate) and some pieces of fruit
Edamame and veggie sushi?
Be sure to always have a luna bar, or some nuts with you.
You do need more calories, fat, protein and whole grains in your diet.
It will take work right now, but just do lots of research and I promise, it will get easier.
, some different food blogs, check out the book 'Becoming Vegetarian' by Brenda Davis and Vesanto Melina for more recipes and nutritional info.
Keep asking questions.
Like I said, it will get easier. It's just a matter of keeping you healthy until then.
Most of the meals I cook take me under 10 mins prep time. It can be done
