Cut 1 large zucchini into thin slices that are about ⅛ of an inch thick (¼ cm), stack up the slices and cut them into 4 evenly sized quarters, finely dice 2 large brown onions, cut 3 cloves of garlic into evenly sized chunks (about 4 from each clove) and crack 6 organic eggs into a large bowl, season them with sea salt & freshly cracked black pepper, whisk together until well combined
Heat a nonstick fry pan with a medium-high heat and add a ¼ cup of extra virgin olive oil, after 2 minutes add the diced onions and the chunks of garlic, mix occasionally to make sure everything cooks evenly, 4 minutes later add the cut zucchini and again mix it all together, cook for about 8 minutes, then season everything with sea salt & freshly cracked black pepper, mix together and remove the pan from the heat
Add the onion and zucchini mixture into the bowl with the eggs and mix together until well combined
Using the same pan, heat it with a LOW heat and add the egg mixture into the pan, make sure everything is evenly distributed, after about 3 minutes run a spatula through the outer edges of the tortilla to make sure it does not stick to the pan, after 5 to 6 minutes it´s time to flip the tortilla (might take less or more, depending on your heat size and pan), place a plate over the pan and flip the tortilla, slide the uncooked part back into the pan, using a spatula compact the tortilla through the outer edges to ensure that classic rounded edge, after 5 to 6 minutes the tortilla should be perfectly cooked, remove from the heat and serve, enjoy!
