Cut the unpeeled potatoes into 2cm-thick chips. Put in a microwave-safe dish and season with salt and pepper. Cover and microwave, stirring halfway, for 6-7 mins until tender. Drain.
Step 2 — Prep ingredients
Meanwhile, coarsely chop the cucumber and tomato. Cut the lemon into wedges.
Step 3 — Season fish
Combine the country seasoning and 1 tbs flour on a plate and lightly season with salt and pepper. Lightly coat both sides of the fish with the seasoned flour, brushing off any excess.
Step 4 — Cook fish
Heat 1 tbs olive oil in a medium frypan over medium heat. Cook the fish for 3½-4 mins each side until golden and cooked through. Remove from the pan.
Step 5 — Pan-fry chips
While the fish is cooking, heat 2 tsp olive oil in a large frypan over medium-high heat. Cook the potato chips, turning regularly, for 4 mins or until golden.
Step 6 — Toss salad and serve
Whisk 2 tsp extra virgin olive oil and 1 tsp red wine vinegar in a large bowl and season with salt and pepper. Add the cucumber, tomato and spinach to the dressing and toss to combine. Divide the fish, chips and salad among plates. Serve with the aioli and lemon wedges.
