Add in sliced onion and cook, stirring occasionally for 5 minutes, then add in the maple syrup and a pinch of salt. Continue to cook for about 10 more minutes until onions are soft and caramelized.
Add garlic and cook for another minute.
Add chicken, rice, beef stock, coconut aminos, salt, thyme, pepper and bay leaves.
Bring to a slight boil, then lower the heat to low.
Add cauliflower then cover.
Cook for 15 - 20 min (or however long your rice package says), checking halfway through to stir.
Then remove the lid and stir. If there is still some liquid, just stir uncovered for a few more minutes.
Remove from heat, remove bay leaves and add gruyere on top and cover for a few minutes to melt the cheese.
Notes
If you want to cook the chicken as part of the dish, just remove the onions once they are cooked, cook the chicken, chopped for 5-7 minutes, then add the onions back in and continue with the recipe.
