Mexican Pizza (way healthier than Taco Bell). (This was actually pretty good, leave in pan and eat from there. and I just used pack of taco mix and ground beef. For my taco pie I didn't use the refried beans, hubby likes the beans though)
Rainbow Layer Cake recipe from Betty Crocker. 2 boxes vanilla cake mix divided and colored with gel food coloring. Idea from comments: Use regular whipped canned frosting for middle layers and Cool Whip refrigerated frosting for the outside.
