The frittata is a versatile Italian dish that has found its way into kitchens worldwide. Traditionally, it was a way to use up leftover ingredients, making it a practical and economical meal. The addition of cheddar and jalapeno gives this version a modern twist, adding a burst of flavor and heat that complements the creamy eggs perfectly. Frittatas are often compared to omelets, but they differ in their cooking method. While omelets are cooked quickly on the stovetop, frittatas are finished in the oven, allowing for a more even cook and a fluffier texture. This particular recipe is perfect for those who enjoy a bit of spice and are looking for a high-protein, low-carb meal. It's a great option for dinner, but can also be enjoyed as a hearty breakfast or brunch dish.
