heat the oil in a (very) large saucepan or saute pan.
dice the garlic and onion and add to the hot oil, frying for a few minutes, then adding in the spices. Fry fr a further 3 minutes and add the chopped bell pepper. You can use any pepper, but i like to use green to add a bit more vibrancy.
Next pour in two cans of chopped tomatoes and stir. Drain the canned lentils and beans (save the bean water as this can be used to thicken other recipes such as soups) and add to the pan along with the sweetcorn, and give it a nice stir. You may need to add some water at this point, or some of the saved bean water.
you may want to add a teaspoon of molasses (black treacle) or dark maple syrup here to add a richer flavour. A square of dark chocolate can also be added instead fot the same depth.
simmer for around 20 minutes. Meanwhile, cook your grains/carbs and prepare some tasty crisp salad to enjoy with it. I like to eat mine with quinoa or rice, some salad leaves and avocado, and maybe some tortillas for that added crunch.
