This goes step-by-step to show you how to build an easy solar oven in 15 minutes or less.
Supplies
Shoebox, cardboard, foil, tape, scissors, and construction paper or black paint.
Step One

Find a normal-sized shoebox and remove the lid with scissors.
Step 2

Cut out four pieces of cardboard from a separate piece of cardboard. They should all be about 4-7 inches wide, closer to 7 would be better, and 2 should be 10-12 inches long, or long enough to match the length of the shoebox. The other two should match the width of the shoebox.
Step 3

Now, cover the cardboard with foil, with the shiny side facing out. Use tape on the backside to hold it in place.

Now either paint the inside of the box with black paint or cover it with black construction paper. Attach the construction paper with either glue or black tape.

Lastly, you need to attach the foil to the box at a 45-degree angle. I did this with duct tape and used cardboard strips to support the foil. You can also have short poles that you put into the ground to support the foil.
