You looking for healthy snacks? Carrots and hummus is a go-to of mine. Another thing you could do for snack/dinner, is a charcuterie board. Throw some cheese, crackers, deli meats, olives on there, cook a batch of meatballs or some other finger foods on the side and you've got yourself quite a bit of food with minimal effort.
I received one of those precision cookers for Christmas to cook things sous-vide but have been so busy with work that I haven't used it yet. Now that I'm working from home I've picked out a few proper recipes to try this week, hoping it works out!
