Yes, as a vegetarian, our meals depend on carbs. I don't think low-carb is the way to go, but personally, when I focus on the carb aspect I end up forgetting the veggies and we eat large amounts of pasta or rice drowning in sauce with a wilty broccoli floret that you can't even see.
I try to keep the vegetables as the focus/main part of the meal or recipe and have the meat (for DH and DS) and carbs as an additive.
