Although we might have to wait a little longer on the release of Mighty Yum, there are other vegan versions of Lunchables out there.
Veganables, which are available for sale online, offer plant-based meats, cheeses, and crackers, in funky tie dye Lunchable-like containers. Little Spoon also offers plant-based lunches with grains, veggies, and plant-based proteins — but it involves less of the DIY aspect of it, with more focus on the food itself.
