Heat a large fry pan with a medium heat and add in the olive oil

After a couple of minutes, add in the sliced onion, mix together, then mix every 1 to 2 minutes

In the meantime, cut the potato into small bite-sized pieces that are a 1/4 inch thick (0.625 cm)

After sautéing the onions for 5 minutes and they're lightly sautéed, add in the sliced potatoes and season with salt & pepper, mix together, then mix every 2 to 3 minutes so everything evenly cooks

While the potatoes are cooking, crack the eggs into a bowl, season with salt & pepper, and lightly whisk together, you want some streaks of egg whites

Cut the zucchini into small bite-sized pieces that are a 1/4 inch thick (0.625 cm), then add the zucchini into a colander with a bowl underneath and season with salt, let it rest for 10 minutes, then transfer the zucchini over some paper towels and pat dry

After cooking the potatoes for 15 to 20 minutes and they're lightly golden fried and cooked through (you can always pierce them with a toothpick), add in the chopped zucchini and mix continuously

Once the zucchini is lightly sautéed, about 4 minutes, lower to a low heat, add in the whisked eggs, and gently mix continuously for 2 to 3 minutes or until the eggs are just cooked through

Transfer into serving dishes and top off with chopped chives, enjoy!
