Red pepper, Tomato and Butter bean curry

No pic for this one - but it's dead easy.  A glut of red peppers and tomatoes after helping a mate cater for a 600 people bash led to its invention.

Sweat chopped celery in oil, add cumin, mustard and fennel seeds. Add crushed garlic, chopped red pepper, 4 diced potatoes and 6 chopped tomatoes. Stir around for a bit. Chuck in some turmeric and chili flakes, stir around a bit more. Add veg stock if it's going a bit dry. Drain a tin of butter beans and chuck them in too, season to taste. Simmer for about 15-20 minutes. Add garam masala simmer for a further few minutes - scoff.
