Heat olive oil in a dutch oven. Add onion and red peppers, saute over medium heat until translucent and soft, about 10 minutes. Add garlic and jalapeno until garlic is just fragrant. Add turkey, cumin, chili powder, and salt. Break up turkey and combine ingredients. When turkey is almost entirely cooked, add crushed tomatoes and simmer for about 5 minutes. Reduce heat to medium-low. Add the mashed up pineapple, beans, corn, and carrots. Loosen up the chili with the reserved pineapple juice, add to desired sweetness. Allow to simmer for 10 to 15 minutes more. Add more salt or chili powder if necessary.
