Lightly spray a medium non-stick frying pan with oil and heat over medium-high heat. Cook the zucchini, capsicum and shallot, stirring, for 4 minutes or until softened. Add the sweet potato and corn and cook, stirring, for 2 minutes. Transfer to a bowl and cover to keep warm.

Lightly beat egg yolks with 2 tablespoons water in a large bowl until combined. Season with salt and pepper. Using electric beaters, beat the egg whites in a large clean, dry bowl until soft peaks form. Fold the egg whites into the egg yolk mixture in 2 batches.

Preheat grill on high. Melt half the spread in the same pan over medium heat. Pour half the egg mixture into the pan. Cook for 3 minutes or until browned underneath. Place pan under grill and cook 2 minutes or until the top is just set.

Spoon half the vegetable mixture over one half of the omelette, sprinkle with 2 tablespoons cheese. Fold omelette over and slide onto a plate. Cover to keep warm.
