Wakame is a seaweed product. You buy it dried and it reconstitutes in hot water. It's the green stuff you get floating in your miso soup. When I make miso, though, it's from fresh miso paste, then I add the wakame after it's cooked.
Pasta in vegie broth is good. I usually just chop up celery and carrot and boil them up then add pasta, and eat it as is. If you wanted to use tortellini or another filled pasta, you could, it's delish.
Frozen spinach cubes are a great wayt o add extra vegies to everything - the Heinz cubes are tiny and so easy to use. You could put two on each of your jacket potatoes. Also works added to any pasta sauce or broth. And voila, there's one more vegie counted towards your 5 a day.
