Butterflied chicken. Can use a cleaver instead of shears, is quite fun to do. Ultra-simple recipe if you skip the jus (which really wont be needed).
Anyway, I've realized I basically don't know what to do with the darn thing! I'm definitely going to put some serious time into baking sweets, and I've always wanted to bake a loaf of homemade bread, but I'm looking for proper meals here and I just... lack the experience? Are there any dishes you would immediately go for in my situation? What would you crave after finally having access to an oven after a good few years without one?
Perhaps a roast is an obvious pick... I'm really not sure, I guess I'm feeling a little overwhelmed now that I've actually managed to sort this cooking situation out.
I'd start getting into the baguette/ciabatta game asap if i got a new oven. Or no knead bread if i didn't have a mixer. Good bread enhances a truckload of meals.
