In a Dutch oven or other large pot, bring one tablespoon of the olive oil over med-high heat. When the oil is hot, add the chopped chicken (if you over-crowd the pan the chicken will not brown, so you may want to do this in two batches) and cook for 6-8 minutes, stirring occasionally until chicken is cooked through. Add the mushrooms and garlic to the chicken and stir together. Continue to cook for another 2-3 minutes until mushrooms are softened. Transfer the chicken and mushrooms to a side plate and cover with aluminum foil until needed. Discard any remaining liquid in the pot.
Add the remaining 4 tablespoons of olive oil to the empty pot and bring over medium heat. When the oil is hot, whisk in the flour, salt and black pepper until combined with the oil and continue to whisk for 1-2 minutes. Slowly whisk in the Almond Breeze Unsweetened Almondmilk a little at a time until combined, creamy and smooth. Add the broth, bouillon and oregano and whisk to combine, scraping up any remaining brown bits from cooking the chicken.
Increase the heat to med-high and stir occasionally until boiling. Add the pasta and reduce the heat to med-low. Cook for 10 minutes uncovered, stirring every 2 minutes or so to prevent sticking.
When the pasta is cooked and the sauce is thickened, reduce the heat to low and stir in the lemon juice, spinach, and the reserved chicken and mushrooms and stir until thoroughly combined. Cook for another few minutes until the spinach is wilted and all ingredients are heated through. Sprinkle with parsley and serve.
