Slice zucchini with a mandolin or food processor. If you don't have any of these things use the sharpest knife you have and slice it the thinnest you can.
2 Set the slices on a platter in a single layer. Drizzle with lemon juice, olive oil. Finish with salt, pepper, basil and nuts.
3 I usually use one part lemon juice for 2 or 3 of olive oil.
