You can pick up a 200g bag of kale for £1 or under from ASDA, Morrisons, Ocado, Sainsbury's,Tesco and Waitrose.Some stores will have done the washing and stalk stripping for you, but check the size of the leaves because if they are too small they may cinder quickly. If you prepare them yourself, you get to decide how big the bite size pieces are. Basically, you wash and dry them unless pre-washed, strip the stalks out and tear into pieces then massage olive oil or another oil into them. You could use pomace oil instead of olive oil (KTC pomace oil is £2 for 1 litre at ASDA, Morrisons, Sainsbury's, Tesco). You could also experiment with other cooking oils, as long as they aren't marked 'For External Use Only'. You can also add pepper and seeds eg sesame. Once oiled, salted, seeded if required, they go into the oven and come out as crunchy snack food. Melissa D'Arabian's recipe from the Food Network. http://www.foodnetwork.com/recipes/melissa-darabian/crispy-kale-chips-recipe.html Kale has 9g carbs per 100g, it's packed with vitamins A and C plus calcium, iron, magnesium, potassium, and vitamin B6 This would be especially usefully if you miss something to munch in front of the TV, or if you're not big on veg or have fussy kids. If you love the crispy seaweed you get from Chinese takeaways or love the salty crunch of seaweed snacks you will lurve kale chips.
