I made my own Tuna Afritada! Need to have a balanced diet so I decided to try experimenting.
At first I already thought of having Tuna with tomatoes but I wanted more veggies and I found mixed veggies in the Fridge. At first I didn't know what to call it but as I was cooking and have put in all the ingredients it looked like an afritada and it seemed like the ones that you buy in the supermarket (Flavored canned tuna).

1/2 canned tuna (I used Century tuna chunks in vegetable oil)
2 tomatoes (diced)
1/2 onion (minced)
1/2 pack mixed veggies
1 1/2 tbsp canola oil

Heat the canola oil in the pan
Saute onion and then put in tomatoes, juice them a bit by pressing on them
add the tuna and saute for 5mins
add mixed veggies and just keep mixing them until veggies are cooked

(Sorry for the terms, but I don't know how to make cooking instructions lol)
