In a pan, add the olive oil, onion, bell pepper, and carrot on a medium-high heat. Cook for 3-5 minutes.
Add the corn, celery, tomatoes, and black beans. Reduce the heat to low and simmer until the tomato juices are lightly thickened, about 7-10 minutes.
Add the chili powder, cumin, oregano, and adjust your seasoning with salt and pepper. Set aside.
Preheat the broiler to 400F.
Arrange a layer of tortilla chips on a baking sheet.
Scatter a generous serving of the chili and shredded cheese over the chips.
Place under the broiler between 3-5 minutes or until the cheese is melted.
Remove from the oven, let cool slightly, then top with sliced jalapeno, fresh cilantro, and avocado.
