The upmarket bangers and mash-based trio all contain Lazenby-branded sausages and come under the Desire banner.
The premium pork sausage recipe comes with garlic and chive mash and caramelised onion sauce, while Cumberland sausage is accompanied by mature cheddar mash and rich wine sauce. Lincolnshire sausage is partnered by honey and mustard mash and port and peppercorn sauce.
Each 500g dish oven cooks in 35 minutes from frozen or takes 12 minutes in the microwave.
The first two variants are already listed in 250 Sainsbury stores, with a two for £4 promotion planned to run across all Sainsbury stores in May.
According to the company, traditional ready meals have lost out to more innovative ethnic recipes in the frozen arena. It claimed its new offerings would appeal to younger consumers.
