An easy way to add some vitamins and fiber, buy a bag of frozen broccoli cuts or other cut veggies and throw some in the boiling water when your pasta is almost done. When they froze it they cooked it a little, so you're really just heating it up while your pasta finishes cooking. Use a rubber band or something to close the bag if you're only using part of it. You can do this with frozen peas, cauliflower, green beans, or other veggies, but not soybeans/edamame! They have to be cooked separately to be sure they're fully cooked, or they can make you sick.

Unlike canned, frozen vegetables retain the nutrients of fresh. And you're not opening the drawer to find they've gone moldy.

I'm having a hard time figuring out, if these exist elsewhere, but over here, I can buy dried soy shreds, which are really great for pasta.

Here's a product I can buy over here, to give you an idea.

So, those are roughly meatball-shaped. There's also smaller one's which kind of work in sauces like minced meat.
They don't taste like meat, more like wheat, but they give you the same protein and chewiness and can be kept in a cupboard basically until the end of time.
