What's for supper? Red, yellow, orange

The colour theme wasn't deliberate--we weren't having a paintbox party--but last night's dinner did turn out to be colourful.  In a good way.

Meat sauce (ground beef, mushrooms, green peppers, a bit of tomato sauce, basil)
Polenta slices, baked and topped with mozzarella cheese and parsley
Sweet potato oven fries
A bit of lettuce from the garden

Sliced watermelon
Apple-butter muffin cake with apple chopped into it (I had promised muffins, but it was too hot to turn on the big oven, so I made a pan of "cake" in the toaster oven instead)
