Great recipe. Delicious, easy, low in calories and high in protein. I increased the veggies so it would contribute more towards our 5-a-day, and served it with homemade oven chips. It did not need cornflour. I used the cheddar as instructed, but substituted the skim milk with unsweetened soy milk and a bit of soy cream. Both my husband and I loved it!

Made this last night, was so nice. I put cornflour in like recipe says but next time I think will leave it out as it's thick enough without it and have more of a sauce. I had it with rice.
