You can roast chickpeas as a snack; heat the oven to gas mark 8, put the chickpeas on a baking sheet, drizzle on a little olive oil and add whatever seasoning you like (cayenne pepper is nice, or smoked paprika would resemble the bbq flavour). Cook them for 1/2hr-40mins.
There are also kale chips, which I expect are dear to buy, but you can make them at home; Preheat the oven to gas mark 4, remove the stems and wash the leaves then drain, put the kale on a baking sheet, drizzle with a little olive oil and mix to spread over the leaves, add your preferred seasonings (chilli flakes are good); bake for 10-15mins.
I have heard that eating excessive salt decreases your sensitivity to it, so as you reduce your intake you'll probably crave salt less.
And congrats on your diet change!
I've seen a similar thing to your kale chips recipe done with swiss chard / beet leaves as well.
And I can also speak personally to the salt reduction issue PV mentioned: I've really tried to reduce my intake of commercially prepared food to virtually nothing. Gave up fast food, rarely buy anything pre-made, virtually no canned goods - they're all full of TONS of salt, often low fat or low calorie products are the worst offenders, because they compensate for the lost flavor from fat by adding more salt. An occasional can of enchilada sauce, some canned broth here and there, that's pretty much it for me at this point. At first, I craved salt. Boy, did I crave salt. But after a while, I grew far more sensitive to salt - if I tried to eat cheetos, OMG, they are almost unbearably salty. Before, they tasted completely normal to me, now, damn salty. This is how I know when I'm being good on the salt front or when I've been lapsing, if I taste a commercial product and don't think "Geez, that's incredibly salty!" then I know I need to get back on the salt wagon. My taste buds give me all the clues I need to know how good I've been (or not been) on the salt front lately.
