I just use Adobo...
has a variety of ingredients to give the eggs a lot of flavor.
I cook the eggs in butter.
But, I’ll try the different things mentioned here.
You can do it many ways
-Adobo, chili oil
-Salsa
-Chorizo
-Ground country ham
-Smoked paprika
That mayo and cream sound right but I use plain yogurt sometimes. I am going to add that Marmite idea.
