First, roast the corn on the gas stove or the bbq. You want some great colour on it, yet not totally black.
Then, chop the jalapeño, cilantro, green onions and the garlic. Mix them all together with the crumbled cheese and add the lime juice, mayo, spices and salt.
Next, set the oven to 400 on roast. Dice the sweet potato into 1/2 inch cubes and toss in the canola oil. Roast for 20-25 minutes. Cut the lettuce into fine shreds.
Once the corn is done cut it off the cob and add it to the mixture of goodness. Then, build your tacos. Sweet potatoes, then lettuce and topped with the street corn. Eat up and enjoy.
