Optional: Preheat oven to 400 and line a large roasting pan with parchment paper. Spread frozen corn on roasting and place in the oven for about 35 minutes until light brown flipping halfway. While corn is roasting place poblano pepper on seperate rack for about 20 minutes until skin chars.
Combine the tofu, milk, mayo, half the cilantro, lemon, jalepeno, dairy free ranch mix, garlic powder, and salt if desired in a food processor and blend till smooth. Pour in a jar and place in the fridge.
In a large bowl add rotel, drianed black beans, defrosted or roasted corn, chopped poblano if desired, and remaining cilantro chopped. Then stir to combine
Add in some garlic powder and salt to taste. I would start with about 1/2 tsp and work up to desired flavor. Then set bowl aside
