1Boil water in a pot and add pasta. Cook until al dente.
2In a wok, melt butter and add garlic and chopped vegetables (onion, green bell pepper, red bell pepper, carrots, corn, and mushrooms). Sauté until softened.
3Add flour to the wok and mix well. Gradually pour in the milk, stirring constantly to avoid lumps.
4Stir in cheese, oregano, red pepper flakes, and salt. Mix until smooth and creamy.
5Add the cooked pasta and the sautéed vegetables to the sauce. Mix gently to coat the pasta evenly with the sauce.
