“It was going into a vegetarian chilli,”
Plain old chili is – by definition – vegetarian.
Chili con carne, chili con frijoles, chili con carne y frijoles – those are something else.
Imagine my surprise when, as a naíve lad of about 13 or 14, when I ordered chili rellenos in a Mexican restaurant, and didn't get what I was expecting. Turned out I I loved it – it's one of my favorite dishes.
