My favorite new thing is a hot bag of beans.
Actually, a steaming bag of lentils and chickpeas.
I came across Tasty Bite meals in a 4 pack at Costco, first the Madras lentils and channa masala the next trip. Zap the bag for 60 seconds and you have yourself a spicy vegetarian lunch (vegan, in the case of the channa masala). And it is tasty! I've been trying to move to a more plant-based diet and though a convenience food, Tasty Bites are a step in the right direction, with a bunch of vegetarian/vegan/gluten free/kosher foods. Today I rounded it out with baby carrots and black bean hummus. Roughage, people, serious roughage.
Downside: a wee bit expensive for an MRE, but they seem to be a responsible company.
