There are quite few really good recipes out there, it depends on how difficult you want them..
Here is one ready in about 30 minutes, I had it printed out a while ago but never got around to making it..Might have to give it a go..I think it might be Rachel Rays.
Vegetable or corn oil, for drizzling, plus 2 tablespoons -- 2 turns of the pot in a slow stream
3 ears corn on the cob or 2 ears fresh-frozen cobs, defrosted (I wonder if you could use canned drained niblets and brown them??)
1 red bell pepper, split and seeded
1 pound chicken breast tenders
1 teaspoon poultry seasoning, 1/3 palm full
1 teaspoon cumin, 1/3 palm full
Salt and pepper
1 small to medium zucchini, small dice
1 medium yellow skinned onion, chopped
3 cloves garlic, chopped
1 to 2 chipotle in adobo peppers (medium to hot heat level), chopped -- available in small cans in Mexican and Spanish food section of market

1 cup shredded cheddar or pepper Jack cheese
1/2 cup sour cream
1/4 red raw onion, chopped

Heat a grill pan to high and a soup pot to medium high. Drizzle oil on corn and place on grill. Add red pepper to grill with corn. Char vegetables 10 minutes, total, turning occasionally. Remove to cool, 5 minutes. Remove charred skin from the pepper.
While vegetables cook, dice chicken. Add 2 tablespoons oil to hot soup pot. Add chicken to pot. Season with poultry seasoning, cumin, salt and pepper. Lightly brown chicken on each side. Add zucchini, onions and garlic and chipotle peppers. Cook vegetables with chicken 5 to 7 minutes to soften. Add tomatoes, tomato sauce and stock. Bring soup to a bubble, reduce heat to medium low.
Scrape corn off cob and add to soup. Chop grilled red pepper and stir into soup. Add chips to soup in handfuls and fold in. Serve soup immediately with scatter of shredded cheese and a dollop of sour cream. Top with any or all of the suggested garnishes.
