Slimming World Hash Browns/Onion Bhajis. Found on a lovely friend's FB page. Hash Brown = Grated potato and finely chopped onion. Squeeze all the liquid out (Use a tea towel for this bit), add salt, pepper and instant potato mix to bind (Cheese onion one) mix with 1 or 2 eggs, shape into patties. Fry light a baking tray and bake at about 180/200 (fan) for 20-30 mins, turning occasionally. Onion Bhaji = onion, coriander, chilli, cumin, lemon juice, instant mash (onion one) and egg/s.
