Tray bakes are quick and easy. You can mix things up and use different meats, spices, herbs and combinations of veg, etc, to give you different flavours so you don't get bored.
Dice some potato/sweet potato/celeriac. Chop some veg, eg peppers, onion, mushrooms, broccoli (or whatever you like/have).
Add some meat, eg, chicken legs, thighs, pork steaks, fish pieces, if you want.
Put it all onto a deep tray.
Sprinkle some herbs and spices over (dried garlic granules are good to have).
I usually add dried garlic, paprika and parsley, but again, go with what you like.
Spray or drizzle over some oil and bake at 180°C for around 30 mins until golden and cooked through. Serve and enjoy.
