Unfortunately Lovecraft would not be eating much homemade food.
One of the many reasons he died so young is because he was beyond frugal with his food spending. Mainly subsisting on free expired or mystery cans (cans that had no label and we're sold cheaper) a single egg (probably also last it's prime) and a bucket (literally a bucket) of yesterday's unsold coffee he bought for cheap from a store down the road.
He would brag in his letters saying things like 'only spent 3 bucks on food today!' (paraphrasing because I can't remember the exact price amounts but way too low. Not just cheap but impossibly cheap)
Seafood pasta would be out of his price range.
