Bring a salted and oil pot of water to a boil and cook your tagliatelle until tender. Drain and set aside.
Prep your ingredients - finely dice the onion, mince the garlic, and slice the mushrooms.
In a large skillet, saute the onion and garlic in olive oil until softened, about 5 minutes. Add the mushrooms and cook covered until tender, about 10 min. Add in the "beef" and cook for 5 min or until crispy. If you want extra crispy pieces, reserve 1/4 cup of the "beef" and cook in your air fryer or oven at 400 degrees for 15-20 minutes or until ultra crispy. Add to the final dish as a topping.
Stir the coconut milk into your mixture. Once it’s started to reduce, add in the pasta and peas.
Serve with optional toppings and enjoy!
