The search engine at Recipe Puppy indexes more than a million recipes, but limits itself to ingredient lists. By stripping out recipes calling for meat, the search filter now offers vegetarian and vegan recipes from sites that aren't necessarily focused on veggies.
A Lifehacker reader asked the Recipe Puppy crew to craft a simple vegetarian filter for their aggregator last year, and the team responded, as that reader explained in our Tips Box. Now custom searches for recipes without meat, or without any kind of meat products, are available at two dedicated, really clean search sites. The sites, like Recipe Puppy, dig through Recipezaar, Epicurious and other foodie favourites to find their results, and are worth keeping tabs on for when you've got a veggie-friendly meal to plan or need to use up some leftover produce.
