Prepare a large skillet and mix in the butter, spinach, cauliflower, and tomatoes. Add a dash of salt and pepper to enhance the flavor.
Pour two beaten eggs on the skillet. Top with the diced ham and cheese and cook for five minutes.
Place the cooked dish in the oven and let it broil for 3-5 more minutes. Remove from the oven and place in a serving dish. Serve while hot.
If you want even a quicker way to make this meal, instead of baking it in the oven for the last 5 minutes of the recipe, consider flipping the whole 'frittata' using one or two spatulas and cook the other side for 1-2 minutes on medium-high heat. This will save you four minutes of cooking time.
