Vegetarian Food Guide Tips On Being Vegetarian?

Tips on being vegetarian? - vegetarian food guide

I Decided to be a vegetarian (which is probably my 3rd time), but I want to do it right. The last time I got sick. Btw I'm a teenager, but I'll try it.
Can someone guide me a kind of vegetarian food, the food should you eat every day, you get all the nutrients and all that I need to stay healthy?
Please give as you can, thanks:)
