(which includes a recipe for 'burgers' made from Sage and Onion stuffing patties flash fried in Margarine), I get the impression that if Hibbert adapted his Pea Curry as per the above the 'Squash' would probably not be of the Butternut variety, more likely the famously "too Orange-y for Crows", Kia-Ora.
To use the Smash Hits-ism...Blurgh! Blee! etc.

that if a hip chef like Heston Blumenthal were to sell the above same dishes in one of his restaurants, rich pretentious twerps would pay handsomely to eat them without question if they were presented correctly

curry was a v tasty snack. Don't know the exact recipe but it certainly contained peas. And potato. And a lovely admixture of cumin, chilli, garlic, turmeric and onion. Served with fluffy, freshly made puris - lovely.

I make a nice curry with paneer and peas. Yum yum.

...is part of the Fabaceae family of plants which also includes assorted beans, lentils ... what we'd call pulses or legumes. Given how central these things are to various world cuisines - the variety of daal dishes in Indo-Pak cooking for example - then "legume curry" of one sort or another (pea, chickpea, mung daal, channa daal, maakhani daal etc) is pretty common. Hibbert with his can of processed peas 'spiced up' may not have produced a masterpiece, but had he done it like Stimpy's FPO up there ^ (fried up a masala with some onion, cumin seed, coriander, turmeric and fresh chilli) then added the processed peas, it would have been fine, a daal basically. (Processed peas are just dried split peas that have been reconstituted in water - some brands chuck in some pretty hideous additives though.)

From a chicken?

of any description are a culinary delight round our way. I love this time of year with all the autumn/winter root veg available for making various types of Asian and North African curries.

Not with mustard and tabasco however but processed peas plus spices, onion, tomato, garlic, fresh chilli etc. Pictured on Flickr (sequence of five snaps, starts with tins of peas). See comments below...
