Place a skillet over medium heat and allow it to get hot. Add oil.
Saute onion, peppers, and garlic until softened, about 5-7 minutes.
While vegetables are sauteeing, place steak strips in a bowl and toss with half of each kind of spice, along with salt and pepper.
Add steak to pan and saute until browned.
Add cauliflower rice and mix well, cook until thawed before adding the tomato paste, remaining spices and water, if needed. (If mixture is too thick to mix in tomato paste, add water.)
Reduce heat to medium-low and cover. Allow to cook about 10-15 minutes, stirring often.
Taste and adjust seasonings. Top with jalapeno peppers, shredded cheese, diced avocado or desired toppings.
