Using an air fryer makes this Fish and Chips as simple as possible for a fast, crispy, and satisfying five-ingredient dinner.
Heat air fryer to 400°F. In shallow bowl, beat egg whites and 1 tablespoon water.
Place chips in second shallow bowl. Dip fish in egg whites, letting excess drip off, then in crushed chips, pressing gently to help adhere.
Spray air fryer basket with olive oil, arrange fish in basket, and air-fry until fish is golden brown and opaque throughout, 10 minutes.
Meanwhile, in bowl, microwave peas on medium 2 minutes. Toss with lemon zest and juice, 1 tablespoon oil, and ½ teaspoon each salt and pepper, then mash. Serve with fish.
