Begin by heating a large skillet over medium-high heat. Add a drizzle of olive oil to the pan.

Once the oil is shimmering, add the sliced andouille sausage. Cook until it’s nicely browned, stirring occasionally for about 5-7 minutes.

Toss in the sliced onions and bell peppers. Sauté for another 5 minutes until the veggies are tender.

Stir in the minced garlic and sauté for an additional minute until fragrant. Then, sprinkle the Cajun seasoning over the mixture, along with salt and pepper to taste.

Pour the can of diced tomatoes (with their juices) into the skillet. Stir everything together and let it simmer for about 10 minutes, allowing the flavors to meld.

After simmering, taste and adjust the seasoning if necessary. Serve hot, either on its own or with your choice of sides.
