We use either coconut oil or palm oil for most fried dishes. These are the cheapest cooking oil products in the local market. Palm oil is the cheaper alternative. For some specialty dishes, I would sprinkle sesame oil. I've never used olive oil or canola oil on a regular basis because it just isn't practical. I only get to use/buy them if they're on buy 1 take 1 promo or when they come free with a product purchase. We start cooking most dishes with oil because it adds more flavor to the food. In some dishes, like stir-fried veggies, we usually start off with butter.
