For Two:
Italian style loaf bread, sliced thick
1/2 lb rare roast beef
1/4 large onion
pesto
Swiss, Leerdammer, or Bleu Cheese (Blue d’auvergene, St Agur, etc)
olive oil
salt & pepper

Heat your panini machine, slice the bread. Dice the onion and place into hot sautee pan with olive oil, adding salt & pepper. Cook until translucent.

Assemble sandwiches–Spread blue cheese on one side of the bread (alternatively layer your cheese), smear pesto on the other peice. Add hot onions against the cheese side, then add roast beef slices. You could also add arugula. Brush the outer sides of the bread with olive oil and grill at medium heat until heated through and golden outside.
