What do you mean 'proper' bechamel? Butter, flour, milk? Can't eat flour (mrs can't, allergic to wheat), and don't eat vegan cheese, it's full of crap and is mostly saturated fats which I'm avoiding as much as possible, with great results.
Best 'bechamel' I've made recently used the liquid that came from the cut-off skin from a celeriac I put through the juicer. The intense flavour came through into the lentil & marrowfat pea lasagne.
