Preheat oven to 350f.
Heat oil in a large, oven-safe skillet over medium heat.
Once hot, add onion and jalapeño, and cook until just tender, for about 4 minutes.
Add zucchini slices, corn and ground coriander and cook for an additional 4-5 minutes.
Season with sea salt and pepper to your taste.
In a bowl, whisk eggs with 1/2 tsp sea salt and pour into skillet with vegetables. Very gently mix to combine.
Transfer skillet to the oven and cook until just set in the middle and lightly golden and puffed on top, about 12-15 minutes.
