PREPARATION TIME: 15 MIN 
TOTAL TIME: 30 MIN 
MAKES: 4 SERVINGS

The genius of an omelette: It works with virtually any leftover (read: forgotten, wilted) veggies hiding in the fridge.

Ingredients
8 eggs
1/2 tsp salt
2 tsp canola oil , divided
1/4 small red onion , diced (about 1/2 cup)
1/2 zucchini , finely diced (about 3/4 cup)
1/2 cup frozen corn kernels , thawed
1 cup packed baby spinach , chopped
1/4 cup canned lentils , optional, drained and rinsed
1 plum tomato , finely diced (about 3/4 cup)
1 cup finely grated cheddar

Directions
Whisk eggs with salt in a medium bowl. Season with fresh pepper.

Heat a large non-stick frying pan over medium-high. Add 1 tsp oil, then onion, zucchini and corn. Cook, stirring frequently, for 2 min. Add spinach and lentils. Cook, stirring until spinach wilts, about 1 min. Transfer mixture to a bowl. Stir in tomato.

Reduce heat to medium-low. In the same pan, add remaining 1 tsp oil, then egg mixture. Cook, without stirring, until edges are set, 1 to 2 min. Use a spatula to lift edge of omelette, pushing toward the centre and tilting pan to allow uncooked eggs to run underneath. Repeat until mixture is almost set and bottom is golden brown, 2 to 3 min. Sprinkle vegetable mixture over top, then cheese. Remove from heat and cover pan until cheese melts, about 5 min. Slide omelette onto a plate and cut into wedges to serve.
