Pour boiling water over the eschallots and allow to cool. Peel with a sharp knife, keeping them whole if possible.
Put the peeled eschallots into a large roasting pan with the Brussels sprouts and drizzle with olive oil and salt, and roast at 200 C (400 F) until golden,
tossing from time to time, around 30 minutes.
Toss the beetroot with a splash of olive oil, balsamic vinegar and salt. Roast uncovered for 45 - 60 minutes, tossing from time to time until the wedges are cooked through.
Boil the podded broad beans in salted water for a couple of minutes. Drain, refresh in cold water and slip out of their skins. Dress with a little olive oil and salt.
In a medium sized salad bowl, toss the fresh rocket and radicchio leaves with a little olive oil, red wine vinegar and then season to taste.
Add the beetroot, escallots, brussels, broadbeans and walnuts. Drizzle more olive oil and red wine vinegar. Season to taste and toss gently.
When ready to serve, spread the goats cheese on the toasts and place them in a hot oven for 5 minutes until the cheese is a little bubbly. Place the toasts in the salad and serve immediately.
