When I’m in a time crunch, I love to make avocado soup! Puree 3-4 ripe avocados with ~1 cup skim milk (adjust based on preference), dash of cayenne & black pepper, hint of salt, and juice of ½ a lime. Top with cooked shrimp and/or cilantro for garnish, and voila! Best if made a few hours ahead, chilled and served cold (great on a hot summer day!)

The craziest thing I’ve ever eaten is fried tarantula (in Cambodia)

After a good workout, nothing beats a glass of cold chocolate almond milk.
