Our Top Picks These vegan options don't quite make a meal, but they can still quell your hunger in a pinch. Keep in mind: All fried options, even if they start off as vegan, may be cooked in the same oil used to cook animal products. If you are concerned, ask your Sonic location about cross-contamination. Onion Rings Completely vegan onion rings are hard to come by, and we're thrilled to find them at Sonic. You can dip these snacks in your choice of ketchup, mustard, and BBQ sauce. French Fries Fries with the skins on get the nod in our book. At Sonic, you have the option of adding toppings to your fries. Make sure to choose veggies only, like diced onions or jalapeños. And don't forget your vegan dip. Custom Slushes In addition to Sonic's expansive slushie menu, you can order a custom slushie with additional vegan syrups. From blackberry tea to blue coconut, there are plenty of plant-based flavor combinations.
