Start boiling water for the pasta. When the water boils, cook the pasta in it.
Get out a big mixing bowl for serving the food in.
While the pasta cooks, if you are using fresh greens, shred the greens into small pieces (a bread-slicing knife works well for this), then add them to the pot where the pasta is cooking for the last couple of minutes of cooking. Or, if you are using frozen greens, defrost them by microwaving them in the big mixing bowl. This takes 5 minutes in my microwave, but microwaves vary so be alert.
Rinse the beans (I like to put them in a strainer and run cold water through), then add them to the big mixing bowl.
Juice the lemon, and add the lemon juice to the bowl.
Add the oil and basil to the bowl.
When the pasta is cooked, drain it and add it to the bowl.
Stir everything together thoroughly.
Serve, with salt and soy sauce available for each person to stir in to their food. If you are using soy sauce, about 2 teaspoons per serving is a good amount to start with.
