Leah lays the roast beef and baked potato on the plate. Reaching for the mozzarella, she spreads it liberally on both. She slips it into the microwave; her dinner - breakfast, actually - has to be quick.
I know, I know, I am the queen of present tense. Although after reviewing my challenge entries, I find only a few in the present. Most of the time I do end up writing past tense. I thought I had done some where I mixed 'em, but I guess I haven't. I'm apparently pretty good at sticking with whatever tense I start the piece with. Maybe I'll try that.

I agree with you, though. Present tense works more for serious, contemplative pieces. Here are two of mine:
A Place for the Lonely
A Different Perspective
