What additional items come with the cheese omelette?

The correct additional items that accompany the cheese omelette are potatoes and toast. This combination is a classic pairing for breakfast dishes, enhancing the meal with both substance and variety. Potatoes can provide a hearty side, often prepared in various styles such as home fries or hash browns, while toast adds a crunchy texture that complements the fluffy, savory omelette. Together, they create a well-rounded breakfast experience, helping to balance flavors and nutrients.

Avocado and salsa, although delicious, are typically not listed as default accompaniments for a cheese omelette in common menus. Mayonnaise and mustard mix does not align with typical breakfast pairings for an omelette. Fruits and nuts might be more suitable for a lighter or healthier option, but they do not typically accompany a cheese omelette in standard breakfast offerings.
