In a large pot, heat the olive oil over medium heat. When glistening, add the onions and sauté for 2-3 minutes or until softened and translucent. Add the garlic, cooking for 30 seconds. Add in the red bell pepper, corn, potatoes, dried basil (if using fresh basil, add it later), and soup stock. Stir, put on the lid and turn the heat up to high. Bring to a boil, then reduce heat to a simmer, cooking for 5-8 minutes or until the potatoes are barely fork-tender.
