Tacos are life!
I'm Mexican-American so I eat tacos almost every day.
I had some breakfast tacos on Tuesday, which consisted of egg, sausage, cheese and spinach with a touch of salsa on corn tortillas, see attached photo.
I had salmon tacos for yesterday's lunch, again on corn tortillas, with a kiwi "pico de gallo" (kiwi, tomatoes, spring onion, lime juice, jalapeños) to add a burst of flavor. See second photo.
Tacos are filled with any vegetable, any kind of protein and are simply folded in a tortilla. As you can see, I prefer corn but flour/wheat tortillas are good too. They are eaten with your hands.
What makes it a taco is that it's folded.
A burrito is usually a flour/wheat tortilla but it's rolled.
A tostada is a tortilla that's been lightly fried and flat, usually a corn tortilla and topped with fillings.
I second the person who suggested the Taco Chronicles. It's an absolute love story about the taco and it's glorious!
I'm off to consider making a few tacos for lunch. Perhaps, guacamole.
