Saute the onion in a small amount of butter or olive oil until soft.

Add the tomatoes and spinach and stir until the spinach is wilted and the tomatoes are heated through.

You can scramble the eggs and cheese with the veggies or separately, I do it all together. The eggs should be soft and fluffy.

Season to taste

To assemble, place a slice of ham on a flat surface with the short end facing you. If the pieces are short, overlap the slices to increase the length.

Spread the filling across the bottom of the slice and roll up. Secure with toothpicks are required.

Repeat with the rest of the ingredients to make 4 roll ups.

Serve as is or prepare a square baking dish with cooking spray and arrange the roll ups seam side down. Scatter some more cheese on top and bake in a 375F oven until the cheese has melted and the ham takes on a little color.
