Dinner, anyone?

On their mission to seek out strange new worlds, going boldly where no Ascalonions have gone before (well, not recently anyway) it would seem they have not had any success in uncovering the Earth's defensive system. Their reports back to their native planet have been mostly negative which may give their masters hope of an early invasion and take over of this third rock from the Sun. (They will have to be quick if they want to get here before the Sun cools down in a few billion years time). Meanwhile, they found this spot in Portugal, the Algarve region, where the local specialty is plates.
LITTLE FLY upon the plate/ Do you think the pattern's great?/ I can't hit you where you sit/ I'll have to wait until you flit.
