Unbelievably Good Banana Curry

I ad-libbed a curry yesterday, and the leftovers were so good today I nearly ate my wife's portion. It's a sweet, very mild curry - which was great for our kids. Adding the banana is something my father does!

Here's the recipe as best I can remember it:

• Fry 1lbs ground chicken or turkey until cooked, set aside;
• In a pot, fry 2 medium onions, 1 zucchini until cooked;
• Add spices, allow them to roast for a minute or two:
  1.5 tsp curry powder
  1 tsp turmeric
  a pinch of cinnamon
• Add the remaining ingredients:
  796mL can of diced tomatoes
  the cooked meat
  2/3 of a medium banana, chopped
  1/4 cup dried currants
  
• Bring to gentle boil, then reduce heat to simmer a bit;
  
• Add salt, cayenne pepper to taste.

Mmm, curry. I forgot garlic, that would probably be good to add.

For a vegetarian version, I usually replace the meat with chick peas (man, I love chick peas) and immediately after adding the tomato I take a wand blender and blend the chick peas, zucchini, onion and tomato until some of it is pureed (makes it nice and thick) but there are still identifiable bits in it.
