Okay, my very favorite meal, not spicy but tangy:
Cuban Churassco Steak.
Salt, pepper, garlic, oil - rub on steak and grill it.
Sauce:
Large bunch of cilantro leaves
6-8 cloves of garlic
1/4 c. vinegar
juice of one lime (you can add more to taste)
2/3 c. olive oil
1/2 c. onion
Throw everything except oil into blender and put on "Chop" but pulse it and don't over blend to a paste. You should see pieces of leaves of cilantro.
Whisk in olive oil. You can add flavor for boldness by adding more lime or cilantro. Put over the steak.
