Add to the pot the black-eyed peas, cooked bacon, water, Ro-Tol tomatoes, chili powder, salt, and pepper. Bring the pot to a boil then turn the heat down to low, cover the pot, and simmer for 1 hour. After this time, remove the lid and continue to cook on low until peas are tender, about another hour. Add more water if the level appears to get too low. Taste and adjust seasonings, and serve warm.
