Heat the olive oil in a large skillet set over medium heat. Add the chicken breasts then season with salt, pepper, and oregano. Cook the chicken for 8 minutes per side.
Once the chicken is cooked, remove it from the skillet and set aside.
Add the butter and chicken broth to the skillet, and cook over medium heat until the butter is melted. Whisk in the flour. The sauce will begin to thicken.
Add the onion and garlic, and cook for 1 minute. Then add the spinach, cherry tomatoes, and lemon juice, and cook for 1 more minute while the spinach begins to wilt.
Add the cooked chicken back to the skillet and reduce the temperature to low. Simmer for 15 minutes.
Chicken is done when internal temperature reaches 160℉. Let it rest for 5 minutes before serving, and the temp will rise to 165℉.
Serve over pasta, rice, or by itself!

Notes
*Boneless, skinless chicken thighs can be used instead. Just increase the cook time by a few minutes.**I recommend using fresh-squeezed lemon juice for the best flavor.Tips:
Be sure to whisk your flour continuously to keep your sauce smooth and clump-free.
Storage: Store Tuscan chicken in an airtight container in the refrigerator for 3 days, or freeze for 3 months.
