I promised you a note about an alternative for sea bass. If you don’t want to splurge on the fish, no worries. You can use a thick filet of cod, or even barramundi. Both are firm in texture, and will hold up to the pan sear relatively well.
Note that with fish that is not as firm as sea bass, you will have to be more careful when pan roasting as they may be more prone to sticking to the pan. But if you can ensure that there is enough fat in the pan (olive oil or butter) as you sear it, and the pan is blazing hot, you have a much better chance of getting the fish to remain intact–and ready for chowing down!
Also, for kale pesto, follow a standard recipe for pesto, only substitute fresh kale leaves for 3/4 of the basil called for in the recipe. It’s a fantastic use for this super green, and adds a light, earthy component that is a super complement to anything it’s used on (fish, meat, pasta, toasty bread–the sky’s the limit!). I’ve also been known to use spinach or other greens for pesto as well. A fun way to get your kids (or in my case, my husband!) to eat more greens!
