Cut chicken breasts into tenders, strips, or just manageable pieces. Add the chicken to a bowl and coat in olive oil. Season the chicken with onion powder, garlic powder, paprika, and chili powder seasoning. If your chili powder seasoning does not contain salt, you can salt and pepper the chicken to taste.
Heat the second amount of olive oil in a large saute pan or skillet on high heat. Once the oil is about to smoke, add the chicken to the pan. Cook the chicken on both sides until the seasonings char in the hot oil and the meat cooks through (time can vary based on how thick your chicken breast is).
Transfer the cooked chicken aside, but return your pan to the stove. Grab your shirataki noodles and drain any water from the packaging. Take out a new, clean pan and add the noodles. Heat on high heat while tossing them every couple of minutes until the excess moisture evaporates and the noodles dry out a little. Try not to brown the noodles.
Keep the shirataki noodles nearby while you melt butter in the first pan you used over a high heat. Once the butter is melted, pour in almond milk and heavy cream. Bring the pan to a boil, then reduce to a simmer. Season the simmering liquid with paprika and garlic powder. Depending on your dietary needs, you may also choose to add a pinch of salt in this step.
Stir nutritional yeast into the simmering pan, then add the shirataki noodles. Chop your chicken breast into small pieces, and add them to your pan too. Stir the ingredients together until everything is well combined in the sauce.
Let everything simmer down until you’re left with a thick, creamy sauce. The noodles and chicken will have eventually absorbed some of the sauce as well. Chop and stir green onion into the pan. You can serve with more green onion on top or with fresh parsley.
