Squeeze the lemon juice into a sterilized jar or glass bottle (easier to mix everything together) otherwise just stir well in a deep bowl).

Add in the olive oil and chopped chives.

To serve, toss with the mixed salad leaves. (Tip: keep the leaves in the bag to keep them fresher for as long as possible, even if its pre-washed being a food clean freak I always have to rinse everything. Normally I'll rinse the leaves in a sieve or colander under running water, and let the leaves drain for about 30 or so minutes.)

Add the sliced avocados onto the leaves. (Tip: Keep the avocados whole until just before serving to prevent discolouration.)

Check seasoning and serve when ready.
