If Brooklyn really wants to be a chef then I'm sure with his parents connections they could find him a great starting position in a top notch kitchen where he could actually learn the skills a chef needs.
I'm a pretty good home cook but I'm not a chef, they are two different things. Without proper training in kitchens Brooklyn has no business calling himself a chef, its laughable. Nigella Lawson was a successful TV cook so it can be done but of course BB lacks Nigella Lawsons charisma and beauty.
I don't see BB wanting to put the hours and work into being a real chef, nor that his new wife would be pleased about the unsociable hours chefs work requires. So I just don't see it happening, although isn't VBs fashion business just a huge vanity project in million of pounds of debt? Perhaps the Beckhams are prepared to plough millions into a vanity project for Brooklyn as well?
