1-First, heat the ¼ cup unsalted butter and 2 tablespoons olive oil in a large skillet over medium-low heat. This combination helps prevent burning and adds a rich taste to the dish. Once the fats are melted and warm, add the 1 small sliced onion and let it caramelize for about 5 minutes, stirring occasionally for even results.

2-Next, toss in the ½ head of cauliflower cut into small florets, 1 pound of cremini mushrooms halved or quartered if large, 1 teaspoon Italian seasoning, salt and pepper to taste, and ¼ cup low-sodium vegetable broth. Turn the heat to medium-high and sauté for around 10 minutes until the vegetables brown nicely, remembering to stir now and then. After that, mix in the 3 cloves of minced garlic and cook for just 30 seconds until it smells fragrant, then adjust the seasoning as needed.

3-Finally, finish the dish by garnishing with ¼ teaspoon red pepper flakes and 1 tablespoon chopped fresh parsley before serving. Tips like stirring frequently for even cooking and slowly caramelizing the onions make a big difference. This whole process takes about 20 minutes, perfect for busy schedules.
