i usually "fry" my ikan billis using the microwave oven or oven. that way, after washing u do not need to worry abt the splattering.
after washing, paper towel dry the ikan billis, then stir it 2 to 3 tbsp of cooking oil (depending on how much u have). put on high for 2 mins, then stir evenly. another 1 min, stir again, then 2 min. it will be cripsy liao.
preheat oven to 180 degree celsius. add oil, stir evenly, place it in oven for 5 mins, then stir it again. put it back in oven & let it roast for 2 mins, & stir again. repeat until u get the right crispyness.
my favorite tofu dish is ma pao tofu. all u need is mince meat & tofu (soft or firm, deepen on wat u like). then go super mart get the ready mix ma pao tofu sauce by Lee Kum Kee, the small red packet one loh, I think it's also call Kuai Ler Chu (happy kitchen). follow the instructions, u will get a very nice tofu dish in less then 10 mins.
