Pre-heat the grill/broiler to high.

Drizzle the pepper pieces with the oil and sprinkle with salt and pepper.

Put them on a baking sheet and cook under the grill/broiler for 8-10 minutes, shaking regularly to brown evenly.  Remove form the grill/briler and set aside to cool.

Put the beef in a bowl with the paprika, lime zest, breadcrumbs, egg, garlic and salt and pepper.  Add the roasted pepper pieces and work together with your hands until evenly mixed.  Divide the beef mixture in half and shape into tow burger patties.  Press each burger down to make them nice and flat.

Put the burgers on a baking sheet and grill/broil for 5 minutes on each side until cooked through.

Slice the bread rolls in half, if using., and put a few lamb's lettuce/corn salad leaves on the bottom half of each bread roll.  Add the cooked burgers and top with a large spoonful of creme fraiche/sourcream.  Finish the burgers with the lids of the bread rolls, if using, and serve with lime wedges, for squeezing.
