This dish is tasty at room temperature and dare I say it, even cold. But if you would like your veggies hot just spread them out on a baking sheet and pop them back into a hot oven at 450°F for 5-10 minutes to reheat them. Or instead, add a swish of olive oil to a castiron iron skillet and sauté for 3-5 minutes. But avoid reheating your veggies in the microwave, that is unless you like them mushy.
