Peel the shrimp. Place the shrimp peels in a sauce pan.
Heat the pan. Add butter and olive oil. Smash the shrimp peels so that the shrimp juices (especially in the head) will be thoroughly squeezed. Add a little bit of salt and pepper.
Add 5 cups of water to make shrimp broth. Stir, boil, then let simmer.
Cut your vegetables (onions, garlic, green beans, cabbage, carrots). Place the vegetable peels in the simmering shrimp broth.
In another pan, add butter or olive oil. Stir fry the veggies one by one (except the cabbage), adding a little bit of salt each time to layer the flavors. Remove from pan.
Half-cook the shrimp, add salt and pepper. Remove from pan.
Strain the shrimp broth into the pan where you stir fried the veggies and shrimp.
Add the rice vermicelli noodles. Cook until soft. Add salt and pepper to taste.
Add cabbage and shrimp (so the shrimp can finish cooking).
Add remaining stir-fried veggies.
Serve.
