Tried these tonight. Did bolognaise tomato sauce using tin tomatoes, onion, yellow pepper and mushrooms (with spices & seasoning) while balls were in the oven and wholemeal pasta simmering. Then mixed all together, sprinkled on low fat cheddar and stuck it back in the oven for 15 mins while washed up.
Verdict - blooming lovely. Plenty for four generous servings, so tomorrows dinner sorted as well.
