THIS adds high-protein plant-based deli slices for sandwiches and picnics

THIS is pushing plant protein out of the burger lane and into the lunchbox, picnic basket and salad bowl with two ready-to-eat deli slices built for everyday use. The move matters because the plant-based category has spent years trying to become a habit, not a treat, and convenience is still one of its biggest tests.

The new line includes Roast Chicken Slice and Butterbean, Garlic and Paprika Slice, both sold in 95-gram packs and designed to be eaten straight from the packet. THAT simple detail is doing a lot of work here: it gives the products a proper deli role, not just a “cook and assemble” role, and puts them squarely into sandwiches, wraps, salads and snacking. The Roast Chicken Slice delivers 19 grams of protein per pack, while the Butterbean, Garlic and Paprika Slice offers 17 grams.

Nutrition is clearly part of the pitch. The Butter Bean, Garlic & Paprika Slices page lists 18 grams of protein per 100 grams, along with 10mg of iron and 0.9µg of vitamin B12 per pack. Both slices are also low in saturated fat, which helps this launch speak to vegans and flexitarians alike, especially shoppers looking for a higher-protein lunch solution that does not mean reaching for meat again. The Roast Chicken Slices page calls the product a tender, deli-style bite and says it is ready to eat straight from the pack.

That positioning goes beyond the product itself. A retail trade write-up said THIS launched the deli slices in spring 2026 for snackers, better sandwiches and premium picnics, and that is the right kind of occasion thinking for this category. Plant-based food has often been boxed into substitution, but deli slices only work if they behave like a staple: portable, familiar, and good enough to keep in the fridge for repeat use. Picnic food is especially smart territory because it forces a product to hold up on flavor, texture and convenience all at once.

THIS has been moving in this direction for a while. The company says it is a plant-based food brand focused on plant-powered protein, and it raised £20 million in Series C funding in June 2024 to expand its range and drive profitability. In April 2025, it launched This Is Super Superfood, a whole-food plant protein range, and in June 2026 it relaunched that line with a mushroom-led name and packaging focus. The broader message is clear: the brand is leaning harder into ingredient-led food and less into category slogans. In a market where deli and grab-and-go sections matter more every year, that is where plant protein has a real chance to become routine.
