Low-carb veggies: Of course there's cauliflowerr, but there's also zucchinii, Swiss chardd, mushrooms, asparaguss, celery, spinach, bok choy, broccoli rabee (rapini), cabbage, broccoli, kale, Brussels sprouts and lettuces (arugulaa, green and red leaf, endive, romainee_, etc.).
Nuts: All nuts are solid choices when you're eating vegetarian keto, but some are higher in fat and lower in carbohydrates than others, such as pecans, macadamias, pili nutss_ and hazelnuts.
Seeds: You really can't go wrong here. Seeds are high in fat, low in carbs and typically full of fiber, which can bring down the net carbs in your meal or snack.
Dairy: Full-fat plain yogurt and plain cottage cheese (avoid flavored high-sugar varieties), hard cheeses and butter.
Eggs: This is arguably the easiest, healthiest and most complete way to get protein if you're eating vegetarian keto. Eggs also give you a nice dose of fat and have practically no carbs whatsoever.
Berries: Strawberries, raspberries and blackberries are all lower-carb fruit choicess_—not because they're low in carbohydrates, but because they're packed with fiber, so your net carbs are low. You'll probably want to skip blueberries, though—a cup will eat up nearly all of your daily carb allotment.
