In a large bowl, mix together Zucchini, Grilled Red Pepper, Salt, Ground Black Pepper, Pepper Flakes, Thyme, and 1 tbsp melted Butter with Rapeseed Oil. Add a dash or two of Pepper Flakes if desired.
Heat the Olive Oil and 1 tbsp Butter with Rapeseed Oil in a large iron skillet over medium-low heat. Add Garlic, Onions and cook gently until the Onions begin to brown, for about 10 minutes.
Increase the heat to medium. Add the Zucchini mixture and continue to cook. Stirring occasionally until the Zucchini is just cooked through and beginning to brown, around 10 to 15 minutes.
Before serving, sprinkle with Parmesan Cheese on top. Serve right away!
Noter
The dish needs to be served right away after it's cooked as the Parmesan cheese will start melting.
You can store the leftovers in the fridge for 2-3 days and reheat it in a nonstick skillet over medium to medium-high heat.
