Works for any sort of green and won't give you tryptophobia:
Choose some pretty robust, flour-only dry pasta shapes (penne rigate, farfalle, but not flat spaghetti/linguine/noodly kinds)
Parboil some horribly healthy green stuff (ideally broccoli, but cauliflower, kale, savoy cabbage, even green beans would work) until softened but NOT completely cooked. Put your pasta on to cook and while it's boiling away, melt 1-2 chopped jarred anchovies per person, a fat clove of minced garlic per person, and half a fresh chili or a pinch of chili flakes per person in a different pan, in some nice olive oil over a very low heat (you really want to be just melting the anchovies and warming, rather than cooking, the garlic. The garlic shouldn't colour at all.) As soon as the anchovies have disintegrated, stir your parboiled and drained veg into this flavoured oil. Then stir through the pasta when that's been cooked and drained. Quick, healthy, not dear, savoury enough not to be completely boring. Even better with loads of grated parmesan or pecorino on it, but this may alienate vegans or people who don't like stinky cheese.
