We've officially swapped Barilla for Reggano pasta. I used to pay about $2.20 for a 1-pound box of Barilla rotini at my local supermarket. At Aldi, however, the same-size box of Reggano-brand rotini costs just under $1. In my opinion, dry staples like pasta and rice are a good place to swap in generic brands. I served the Aldi rotini with marinara sauce and my kids gobbled it up.
For a traditional double pie crust a [vegan] butter substitute is the best option because it tends to cool and melt similarly to real butter. My two favorite brands are Monty's and Miyoko's.
