Heat the olive oil in a medium pot over medium-high heat.
Add the ground beef and cook until browned, breaking it up with a wooden spoon as it cooks.
Stir in the diced yellow onion, red bell pepper, and minced garlic, sautéing until the vegetables are tender.
Add the chili powder, smoked paprika, cumin, sea salt, and black pepper, stirring for one minute to toast the spices and release their oils.
Pour in the tomato puree, kidney beans, and water, then bring the mixture to a gentle boil.
Reduce the heat to low and simmer for 15 minutes until the chili is thickened and the flavors have melded together.
