Turn addictive spinach-artichoke dip into a creamy filling for grilled cheese sandwiches. A frisee and pear side salad balances the rich sandwiches with tart and sweet notes.
Heat a non-stick frying pan or skillet over medium-high. Add oil and garlic and artichoke hearts to heated oil. Saute until garlic is fragrant, ~1 minute. Add spinach and a pinch of salt. Saute until spinach is wilted and most of the liquid has cooked off, 3 to 4 minutes.
Transfer spinach mixture to a mixing bowl and allow to cool slightly. Stir in mayonnaise and cheese. Season with salt and pepper, if needed.
Wipe out pan and return it to heat.
Assemble grilled cheese sandwiches by buttering one side of each piece of bread. Place half the slices of bread buttered-side down in hot pan. Top with spinach-artichoke filling and then add remaining bread, buttered-side up. Cook until bottom of bread is golden brown, ~3 minutes. Flip and cook on the other side until filling is completely melted, ~3 minutes more.
While sandwiches cook, whisk together mustard, honey, vinegar and oil. Toss with pears and frisee.
Slice sandwiches and enjoy with salad on the side.
