Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to cook bacon in the toaster oven [title] Line a baking sheet with aluminum foil. [step] To start, take out a baking sheet that will fit in your toaster oven. Line the baking sheet with aluminum foil.

Ending1: This will make clean up easier afterwards, as you can simply remove the foil and discard it. [substeps] If you don't have aluminum foil, you can use parchment paper instead. Ending2: Your aluminum foil will keep the temperature in your toaster oven inside out so there is less oil. Spread the bacon grease liberally all over the pan, coating the entire pan completely with the grease. Ending3: You will then arrange the chicken breast-side down in a single layer on the foil. Continue layering around the pieces of chicken breast until all the pieces are completely covered in foil. Ending4: Ensure that the foil attaches firmly to the sides and top of the baking sheet. You do not want to melt the foil, as it will not cook properly and breakage will be caused.
