Portobello Mushroom Burger

One of my brazilian friend always mentioned about portobello mushroom burgers an I thought to myself how on earth would mushroom burger taste without meat or veggies in it! However, I decided to give it a try from one of Betty Crockers cook book fearing the results of EAT(eater acceptance test).Keeping in mind my eater(Hubby the great) I tweaked the recipe a little and it turned out to be absolutely lip smacking!!

Ingredients: Makes two burgers.

Marinade:
2 tbsp- Olive Oil
1/2 tsp- Thyme *
1 pinch- Rosemary
1 tbsp - Dijon Mustard
1 tbsp - Honey Mustard*

1/2 tsp- Freshly Ground Pepper
1/2 tsp- Hot Sauce1 tbsp - Grated lemon peel
1 tbsp - Grated Grapefruit peel (Optional) *
Salt to taste.
2 Portobello mushrooms- Clean wiped
1 number - Sliced Onion.

Assemling:
MayonnaiseLettuce leaves
Sliced Tomatoes
2 slices of provolone cheese *
Burger Buns.

In a wide container add all the marinade ingredients and mix well. Rub the marinade on the mushrooms so that it coats both the sides evenly.Mix in the onions in the marinade.Heat the grill pan. Place the mushrooms and onions on the grill pan till the mushroom is cooked on both the sides and the onions are caramalized.Rub the remanining marinade(if any)when you flip the mushrooms and onions everytime.Spread mayo on the burger buns,place the lettuce leaves,mushroom patty,caramalized onions,cheese,Sliced tomatoes.
