Mix the red chilly powder, fresh lime juice, salt, pepper, turmeric powder and garlic powder together.
Wash the fish pieces and dry them with a paper towel. Apply the masala(spice rub) mixture into the fish.
Line a baking tray with aluminium foil. Place the fish on the foil and bake it for 30-35 mins at 425F.
If you want a nice crispy crust, broil it during the last 5 minutes.
Make sure you keep an eye on the fish while you broil it because it can easily burn the fish.
NOTE :
1)I usually make this in my toaster oven. Each oven or toaster has different capacity so please watch the fish while baking to make sure that it doesn`t get burnt.
You can substitute vinegar or Lemon juice with Lime juice.
You can use fresh garlic instead of garlic powder.
