Place chicken and salsa in the bowl of your slow cooker. Cook on high for 4 hours or 6 hours on low. Before serving, shred the chicken between two forks.
Heat the cauliflower rice:
Stovetop: heat a large non-stick pan over medium-high heat, and add the oil to warm it up. Add the riced cauliflower and sauté for about 5 minutes until the cauliflower rice is heated through and tender.
Microwave: place the cauliflower rice in a microwave-safe bowl with ¼ cup water. Cover with plastic wrap to trap the heat in. Heat it for about 4 minutes, stopping to stir once or twice to ensure even heating. If you're using frozen riced cauliflower, you can steam it in a bag and follow the package directions.
Once the cauliflower rice is hot, add the cilantro, and stir to combine.
Build your bowl:
Add a base of cauliflower rice and top it with shredded salsa chicken, cheese, guacamole, black olives, sour cream, and additional cilantro.
