Combine polenta and water in a medium-size bowl. Allow to sit for 5 minutes. Stir through egg and milk. Then fold in flour and mix until mixture is smooth.
Heat a non-stick frying pan over medium-low heat. Spray with olive oil. Pout 2-teaspoon portions of mixture around the pan, allowing room for spreading. Cook for 1 minute or until bubbles appear. Turn and cook for a further 30 seconds or until golden brown. Repeat with remaining mixture.
Combine cottage cheese, lemon juice and 1 tablespoon chives. Spread pikelets with cottage cheese mix and top with salmon and chives.
