Low carb pasta substitutes that are not zucchini?

My boyfriend and I are slowly switching over to a low carb diet. The main focus right now is cutting back on pasta. We recently discovered he does not like squash/zucchini so zoodles are out of the question. We have been eating whole wheat pasta but I'm left wondering if there's anything else he might like.

He's really picky when it comes to veggies but we have found that the less squishy the texture, the easier it is for him to stomach.
