Place a skillet over medium-low heat, and add pine nuts. Shake pan every few minutes to avoid burning. When you begin to smell a light toasted nut smell, turn off heat and reserve pine nuts.
In the same skillet, add a drizzle of olive oil and place over medium heat. Add spinach and cook for 2-3 minutes until wilted, then remove from heat and reserve.
Place the skillet back over medium high heat, add chicken, season with salt and pepper, and saute until cooked through. Remove chicken from skillet and reserve.
Put the same skillet over medium high heat once again and add a splash of olive oil. Add onions and cook until they begin to brown.
Add garlic and cook a minute longer. Add beer and turn heat down to low. Cook until liquid is reduced by 1/3.
Whisk in flour and cook while stirring for a minute or two. Turn off heat and set aside to cool while to begin assembling your pizza.
