Add chorizo to the pan and cook.
Once choirzo is cooked, remove from pan. Add chicken in the grease from the chorizo to cook.
Remove chicken once cooked. Add onion and pepper to the pan and saute until slightly soft. You might have to add a bit more oil to saute the veggies in.
Add garlic and spices to pan.
Add riced cauliflower and cook until just slightly tender. You don't want mushy paella.
Add chicken and chorizo back to the pan.
Add tomato paste, tomatoes and some of the chicken stock. You don't want it to be too runny so you will have to eyeball the amount of stock you add.
Place shrimp into the liquid and cook with the lid on until the shrimp is pink. You want to arrange the shrimp in a pretty pattern and push it down into the liquid.
Once the Paella is cooked it is time to sprinkle with parsley and drizzle the juice from the lemon over the top.
