Baked Avocadoes

Oven-baked avocadoes stuffed with tomato sauce and topped with cheese. Never knew you could cook avocadoes like this but it really works, they are gorgeous. I freeze small portions of my own tomato sauce so I always have some available when making this, and I use Parmesan or similar hard cheese - cheddar is too greasy and slides off while cooking.

NB - gave this book away recently and can't remember the exact title of the recipe.
