- Cook ziti pasta according to package instructions until al dente; drain and reserve. 
- In the meantime, heat olive oil in a saucepan over medium-high heat. Once hot, sauté the onion for about 3 minutes or until tender and translucent. 
- Then, sauté the garlic for about 30 seconds, until aromatic. 
- Cook the vegan ground beef for about 4 minutes, stirring continuously to promote even browning. 
- Next, stir in the marinara sauce and continue to simmer, partially covered, until your sauce has thickened slightly. Sprinkle with spices and stir to combine. 
- Place the cashews in the bowl of your food processor or high-speed blender. 
- Add in the remaining ingredients for vegan Mozzarella sauce and blend until everything is well incorporated. 
- To assemble baked ziti, grease the inside of a casserole dish with nonstick cooking spray. Spoon a ladle full of the “meaty” sauce into the dish; spread it across the bottom of the dish. 
- Add 1/2 of the cooked ziti, then 1/2 of the sauce on top. Gently toss to combine. Spoon 1/2 of the cheese sauce. Repeat layers one more time. Top with vegan mozzarella. 
- Bake in the preheated oven at 350 degrees F for about 25 to 30 minutes (or until the cheese is melted) on the middle rack in the oven. 
- Bon appétit!
