Dice the chicken into small bite-sized pieces (about 1 inch).
In a bowl or bag, combine chicken with taco seasoning, lime juice, and 1 tbsp olive oil. Mix well and let marinate for at least 10 minutes.
Heat the remaining oil in a large skillet over medium-high heat.
Add the chicken and sear for 1–2 minutes per side until lightly browned.
Stir in the garlic and cook briefly until fragrant.
Increase heat to high, then add diced tomatoes with green chiles and cauliflower rice.
Bring to a boil and cook for 3–5 minutes until liquid reduces and thickens.
