Prep the chicken by cutting each breast in half and tenderizing it into 1/2 thick pieces.
Combine the almond flour and tapioca starch. Coat the chicken pieces thoroughly in the mixture.
Heat half of the butter in a pan on medium heat. Cook the chicken for 5-10 minutes per side, or until thoroughly cooked.
While the chicken is cooking, start cooking the pasta and prep the sauce.
For the sauce, combine the broth, wine, lemon juice and Dijon mustard.
Once the chicken is cooked, remove and set aside. Add the other half of the butter, garlic, & onion to the pan & cook for 2 minutes on medium heat.
Add the sun dried tomatoes and let cook for about 5 minutes.
Add the sauce mixture to the pan & bring to a boil. Turn down the heat and let simmer until the pasta is almost finished. You can also add the chicken back in to keep warm.
When the pasta is almost finished, take out the chicken and add in the oat milk, capers, and spinach. Cook for 2-3 minutes.
When pasta is finished, add the pasta with a small amount of pasta water and combine.
