Heat Things Up: Start by grabbing a large skillet or wok. Drizzle in that vegetable oil and get it nice and hot over medium heat. You want it sizzling, but not smoking!
Sauté Away: Throw in the diced onions and sauté for about 2-3 minutes until they soften up. Then, add the minced garlic and bell pepper, cooking until everything is fragrant and the peppers are slightly tender, about another 2 minutes.
Time for the Fun Stuff: Now, if you’re using chicken or shrimp, toss that in next. Let it warm through for about 2-3 minutes. Next, stir in the frozen peas and carrots, and give it a minute until they're heated.
Bring on the Rice: Here comes the rice! Gently add your cooked rice—day-old rice is best because it’s a bit drier and fries up nicely. Break up any clumps with your spatula, and mix it all together!
Spice It Up: Now sprinkle on the Cajun seasoning, soy sauce, and Worcestershire sauce. Stir it like you mean it, coating all the rice and veggies with that delicious flavor. Allow it to fry for about 5-7 minutes, stirring occasionally. Let those flavors meld!
Taste Test: Take a taste! Is it spicy enough for your liking? Adjust with more seasoning, salt, or pepper. Once you’re happy with the flavor, it’s almost time to eat!
Garnish and Serve: Plate it up, sprinkle some chopped green onions over the top, and you've got yourself a beautiful Cajun Fried Rice!
