Fish sticks great on their own, but let's round them out with sides. The fun part is choosing what goes with fish sticks. Here are a few suggestions, each of which is delicious.
Heat oven to 200C/180C fan/gas 6. Pour the beaten egg into a shallow dish. Tip the breadcrumbs onto a plate. Combine the oregano, salt, and pepper with the lemon zest in the breadcrumbs.
Brush a non-stick baking sheet with half the oil. Dip the fish strips into the egg, then roll them in the breadcrumbs. Transfer to the baking sheet and bake for 20 mins until golden.
Meanwhile, mix the mayo with a squeeze of lemon juice. Toss the spinach leaves and peas with a squeeze more lemon juice and the remaining oil. Serve the fish fingers with the spinach and peas and a spoonful of the lemony mayo.
