I never thought ramen was vegetarian. I mean.. don't the flavor packets have a broth in them?
If you are going to be vegetarian, you have to do it right. Obviously, you're not doing it right, or you wouldn't have missing enzymes and protiens and be taking suppliments and such. Eating fresh(or frozen) fruits and vegetables and a lot of beans, rice, grains, and making sure it all balances out is not a easy thing.
Those pre-processed foods are expensive and unhealthy in general anyway.(Ramen being the probable exception) You can get a lot of dry pasta and real cheese and such to make mac n'cheese, and it's not much more expensive.
The vegetables, dry pasta, dry beans/lentils, cheeses, and grains can be bought in bulk, and stored in the freezer if necasary. Barley put into soups is also awesome and bulks up a soup nicely.
You might have to start buying some of your own foods, and checking into what makes up a proper vegetarian diet, so that you can eat vegetarian without any deficiencies.
I personally think that a human can live on a vegan diet, if it's properly balanced out with the necasary nutrients. I won't ever be vegetarian(and esp not vegan), I like meat. I try to eat a lot of in-season fruit, and I like steamed veggies too.
Good luck. Stay away from all processed foods, snack foods, instant foods, and such. It's part of the healthy lifestyle you seem to want anyway, and that way you should stay out of the MSG as well.
