Note: If using a Vitamix, soup should heat up as it is processed. Alternatively, ingredients can be blended, transferred to the stove, brought to a boil and reduced to a simmer for 4-5 minutes.
Pre-heat a skillet over medium heat (non-stick is preferable). Spray the pan if necessary. Generously butter the outside of two slices of bread. We used about 1 T of butter per sandwich. Place one slice of bread with its buttered-side down onto the skillet. Add 2 slices of cheese and place the second slice of bread on top, buttered-side-up.
Grill the sandwich for 1-2 minutes or until lightly browned, and then flip over. Once cheese is melted and both sides are browned, remove from skillet. Wait a minute for it to cool. Then, use a cookie cutter of choice to cut shapes into your grilled cheese.
Serve grilled cheese cutouts with tomato soup. We also microwaved some frozen veggies on the side for extra nutrients.
