Preheat oven to 375.
Wash the sweet potatoes and chop the ends off. Chop into 1/2 inch squares and lay on a baking sheet with a few dallops of coconut oil.
Cut the extra cornsilks (strings) off of the end corn but keep the husks on. Rinse with water.
Put the full corn husks (no baking sheet) and sweet potatoes in the oven.
Bake the corn for 30 minutes and the sweet potatoes for 45, stirring every 15 minutes.
Chop the ends off the cucumber and slice in half lenth-ways. Cut out the seeds, and then cut lengthwise 3-4 more times and then cut into pea-size cubes. Add them to a large bowl.
Drain and rinse the black beans (or use freshly cooked), and add to the bowl.
Thinly slice green onions and add to the bowl.
Add cilantro and hemp seeds to the bowl.
Allow the corn and potatoes to cool. Slice the corn off of the cob and add both to the bowl.
Add the apple cider vinegar, salt and pepper to the bowl and mix everything together well.
Mash up the avocados and stir into the salad (with hot sauce if using). If storing in the fridge for more than a day, wait to add the avocado until ready to serve.
