Heat the olive oil in a small pot over medium-high heat.
Add the diced yellow onion and green bell pepper, sautéing for 3-4 minutes until the vegetables are softened.
Add the ground beef to the pot, breaking it up with a wooden spoon, and cook until completely browned.
Stir in the chili powder, cumin, garlic powder, sea salt, and black pepper, allowing the spices to toast for 1 minute.
Pour in the tomato puree, rinsed kidney beans, and water, then stir to combine.
Bring the mixture to a gentle boil, then reduce the heat to low and cover with a lid.
Simmer the chili for 15 minutes to allow the flavors to deepen and the sauce to thicken.
While the chili simmers, toast the sprouted grain bread until it is golden and firm.
Ladle the hot chili into a bowl and serve immediately with the toasted bread on the side.
