This is a classic Italian pasta dish. We grow this broccoli (rapini) in our garden easily whereas here in Canada it's $2.50 a bundle and difficult to find.
Wash and trim off the thick stalks.
Boil the broccoli leaves and flowerettes until tender (7 mins) to remove bitterness.
Transfer to the saute pan with approx 3 tbsp of cooking water on low heat with a large chopped clove of garlic, salt, olive oil and hot pepper (optional)
Cook pasta in broccoli water (salted)
Drain pasta and add to the saute pan for 1 min to toss.
