Cook the Chorizo: Heat olive oil in a skillet or shallow pan (with a lid) on medium heat. Add the chorizo and brown it until it is golden and fully cooked for about 12-15 minutes. Transfer the chorizo from the skillet to a paper towel-lined plate for soaking up grease and cover it with foil to keep the chorizo warm.
Saute the vegetables: Stir in garlic, onions, peppers and celery to the skillet juices and saute them until fork tender.
Stir in the cauliflower rice: Mix in the riced cauliflower to the ‘Holy Trinity’ (veggies) and cook until it becomes slightly translucent about 3 mins.
Add the spice blend and tomatoes: Stir in the spices and tomatoes (with juice) to the skillet, cook for about 2 minutes and let the tomato juices soak into the veggies. Turn up the heat a little so that everything becomes even in temperature.
Cook the Shrimp: Bury the shrimp into the mixture, cover the skillet with a lid and let the Jambalaya cook for about 5 minutes until the shrimp have turned pink and cooked through. Try not to overcook the shrimp as it will become too dry.
Slice and add the Chorizo: While the shrimp is cooking, slice the chorizo into small ½-inch pieces at a diagonal, then add them to the cooked shrimp and give everything a big stir to mix it all up.
Garnish the Jambalaya: Switch off the stove, transfer the skillet to the table, and garnish the Jambalaya with chopped cilantro and an extra sprinkling of homemade Southern spice blend.
