Heat a dash of oil in a medium sized deep pan. Add the onion and celery stir-fry over a medium low heat until vegetables softened. Add the garlic and mushrooms and stir-fry a further 2 minutes. Pour over Wattie’s Crushed & Sieved Tomatoes. Add Gregg’s Rubbed Oregano. Stir while bringing to a boil. Reduce heat. Add Wattie’s Red Kidney Beans and Wattie’s Lentils. Stir and simmer for 10 minutes, until legumes are heated through. Season to taste with a pinch of sugar and salt and pepper, adding a splash of balsamic vinegar if wished.
