I've noticed a lot of dishes that undergo alterations to become vegetarian usually end up spicy. Is it because spice covers up what's lacking? For example, I get a chicken stir fry a lot at my favorite Chinese place in town. One time I decided I wasn't in the mood for meat and went with the vegetarian option, but it was spicy when the other options weren't. And another example: on lasagna day my workplace serves veggie and regular lasagna, and the veggie one always has a kick to it. Same with all the MRE's I've eaten, vegetarian MRE's are something "spicy" 90% of the time.
