I love shirataki, but only for certain things like soup, and and cheese, chinese sesame peanut sauce!, Curry or pesto or alfredo....ha, that was long list.
It doesn't work very well with marinara or scampi or Kugel IMO.

You might also try using other veggies as bed for "rice/pasta." For example, we love roasted broccoli or broccoli slaw under marinara and meatballs. Spinach is another great base under sauce/ meat balls.
spaghetti squash is a fun way to switch up and makes great kugel.
"Zoodles" or socialized zucchini is amazing.
I have even seen spiralized butternut squash and beets.....
