Combine 1/4 cup of whole wheat flour with garlic powder, red chili flakes, oregano, salt, and a few grinds of black pepper into a shallow bowl. Set aside. In another bowl, whisk together egg, water and 1/4 cup whole wheat flour.
Place a large pan on your stovetop and set to low heat. Once pan is hot, pour in olive oil from both cans of sardines. Let oil heat up.
Carefully dip one sardine at a time into wet mixture. Use a fork to assist with this. Remove sardine from wet mixture and add to bowl of flour and spices. Coat each side with flour.
Once oil starts to simmer, carefully add in your battered sardines. Flip over after 4-5 minutes or until golden brown. Remove sardines from oil and place on a dish lined with paper towels to soak up any excess oil. Serve over a salad or with your favorite veggies.
