I often see this advice - to use non-meat proteins as prices rise and it's very good advice. Except, unfortunately, for many who suffer from IBS or other digestive related conditions who can't tolerate beans, legumes, and many other non-meat options. Pastas are good, but they are higher/denser in calories and not really a complete nutritional offering.
As pricey as it gets, lean fish, chicken, etc is healthy, nutrient packed and often kinder/gentler on sensitive digestive systems. But luckily there's Aldi's, Walmart and others who are managing to keep most prices in the reasonable range - aaaand of course smaller portions of the protein help
