Because making anything more ambitious is beyond me right now.
There’s a recipe of the same name already, but this is substantially different, hence the “Alternative version”. Eat with good bread or, for a change, crackers, for a decent protein hit. Crumbling crackers into soup is very much an American habit that popped up in the UK with the introduction of Saltines (late 50s, early 60s if memory serves), which then vanished. You can buy them again (try Amazon), but the price is absurd (in excess of £6 per 1lb box). Try Krackawheat instead. They never seem to be truly fresh and crisp these days, but are fine broken up and tossed into a bowl of soup and eaten while they still have some crunch.
