Increase Carb intake?

I have been on a CGM for a large amount of this pregnancy. Recently, my insulin resistance is definitely increasing. My provider wants me to increase my carbs? Any ideas on how to do this! We are a very veggie and chicken and Greek yogurt type of household. Carbs are not something we keep alot of on hand aside from occasional starchy vegetables or sprouted breads. How do you possibly get more carbs in? For reference, I am eating around 75 g of carbs a day, mostly from my fruits and veggies and peanuts I eat. What carbs are people eating?
