Preheat the grill to medium and grill the sausages to pack instructions for 15-20 minutes, turning frequently until golden and cooked through. Remove and slice on the diagonal.
Meanwhile, heat the oil in a deep frying pan over a medium heat. Add the chopped onion and garlic, turn up the heat and cook, stirring occasionally, for 3-5 minutes until the onions are turning golden and the liquid has evaporated. Add the peppers and cook for 2 minutes.
Add the mixed beans in chilli sauce, chopped tomatoes, chipotle paste (if using) and sweetcorn to the onions in the frying pan, bring to a gentle simmer and cook for 10 minutes.
Meanwhile, cook the rice bags to pack instructions; on high for 8 minutes.
Just before serving, stir the cooked sausages through the spicy sauce. Serve the chilli with the rice and a sprinkling of the grated cheese if you wish.
