Merry Mel,, thought I'd copy and paste Elizabeth Knappert's recipe for you. I was just in my emails so I thought it would be easy to do. Here you go:
"cook the penne as normal, mash an avocado with the zest and juice of a whole lime. mix with the pasta, finely chop a small shallot. finely chop cherry tomatoes, red bell pepper, green leafy lettuce. (I used lambs lettuce) blanche some green asparagus tips just long enought o take the rawness off them. mix and eat. No salt, No oil. (You can add salt to taste)"
