It’s true. I wish that Wikipedia would amend its misleading entry which cites a misleading source.
There are so many variants of sinangag. Regional variants, carinderia variants, socio-economic variants. Let’s even include those which aren’t new variants but copycats christened with catchy names for marketing purposes.
I don’t know every existing variant of sinangag, but these are some of the ways we cook it at home.

Java rice – A fried rice that often accompanies grilled food served on a heated cast iron plate, Java rice may look like Indonesian nasi kuning but it is really more Filipino than Javanese or Indonesian. Get the recipe.

Garlic fried rice – Don’t take short cuts by simply sprinkling fried garlic on top of fried rice. Fry pounded garlic in oil until golden and crisp, scoop out, stir fry the rice in the garlic oil and stir in the crispy garlic. Get the recipe.

Egg fried rice – Rice that had been allowed to sit and dry out, on the table or in the fridge, is ideal for fried rice. You just can’t stir fry hot rice and expect brilliant results. Use ground white pepper if you don’t want tiny black specks on your cooked egg fried rice. Get the recipe.

Salted duck egg and garlic fried rice – Store-bought salted duck egg yolk paste was combined with lightly fried garlic to make the base for this fried rice dish. Enjoy the rice by itself or serve as a side dish. Get the recipe.

The ultimate Filipino fried rice (sinangag) – Make fried shallots and garlic, then use the flavorful and aromatic oil to cook your rice in. Serve your sinangag topped with the crispy shallots and garlic, and add sliced scallions for color and even more flavor. Get the recipe.
A bonus:

If you have no great plans for the weekend and prefer to take it slow and easy, may I recommend a great watch on Apple TV? It’s called Silo. It’s a sci-fi dystopian drama adapted from the trilogy of novels (Wool, Shift, and Dust) by author Hugh Howey. Two seasons, each with 10 episodes, are available for streaming.
