Cook the spaghetti according to package directions until al dente. Before draining, reserve about 1/2 cup of the starchy cooking water. Drain the pasta.
While the pasta cooks, heat the olive oil in a large skillet over medium heat. Add the minced garlic and cook for about 30 seconds until fragrant. Do not let the garlic brown.
Add the ground turmeric and black pepper to the skillet. Stir constantly for 15 seconds to toast the spices.
Add the cooked noodles, cauliflower (rice or noodles), salt, and nutritional yeast (if using) to the skillet. Toss well to coat everything evenly with the spice mixture.
Pour in the lemon juice and about 1/4 cup of the reserved pasta water. Toss continuously until a light sauce forms and coats the noodles. Add more pasta water if the mixture seems too dry.
Serve immediately.
