Broccoli and Cauliflower Gratin

1 small cauliflower
1 small head broccoli
1/2 cup plain yogurt
1/2 cup grated cheddar cheese
1/2 tsp ground mustard
Breadcrumbs, salt & pepper

1. Cook cauliflower and broccoli pieces in boiling water for 5 mins.  I use Stream Fresh pouch (no preservatives, no additives) and steam for 3 mins.

2. Mix together - yogurt, cheddar cheese, mustard powder, salt & pepper in a bowl.  Spoon over broccoli and cauliflower.

3. Pre-heat your toaster or oven to moderately hot.  Sprinkle bread crumbs over the top of vegetables.  Bake until golden brown.  Best when hot.
