One of the most famous and popular is Banta. I bought their spaghetti made from chickpeas.
The company has several different different types, from this and angel hair to lasagna strips to elbow macaroni. There's even kid pastas from wagon wheels to alphabet. It takes about the same amount of time as regular pasta and tastes almost the same too. There is a slight chickpea aftertaste.
The texture too is the same and didn't clump the way wheat based spaghetti does. The only disconcerting aspect is that the water foams up while boiling. This can be easily skimmed off. More traditional companies such Ronzoni and Barilla are also jumping on the band wagon.They're using vegetables such as cauliflower, carrots, spinach and tomatoes instead of beans. There's also their Super greens composed of spinach , zucchini, broccoli, parsley and kale. Barilla is also offering chickpea pasta too as well as red lentil. Red lentil spaghetti is a fun and healthy way to enjoy a traditional pasta.
Traditional wheat pasta is making way for a new type. It's much more healthier and even tastier. What's great is that you can make it as just as classic and delicious as the original ones.
