After making this sandwich nearly every day in the summer, this Boursin tomato sandwich really is the most delicious lunch...ever. And with juicy tomatoes and crispy garlic bread, it's elevated enough to serve to friends and family. (Ready in just 15 minutes, so you can spend more time enjoying your company and less time preparing food!)
Prep Tomato: Slice the tomato into thin slabs and lay it on a paper towel. Sprinkle with salt and pepper. Let sit while you gather everything else, then pat slightly dry.
Assemble: Build the sandwich by spreading Boursin onto a slice of sourdough, then layering on the tomatoes, basil, and optional spinach, topping with the other slice of bread. In a separate bowl, stir together margarine and garlic. Spread garlic mixture onto the outsides of the sandwich.
Cook in a skillet over medium heat until both sides are toasty and golden brown, about 3 to 5 minutes per side.

Notes
Storage: I wouldn't say this sandwich is great for leftovers because of the moisture in the tomatoes. Try to make only what you think you'll eat right away.Tips for slicing tomatoes: You either need a very sharp knife or a serrated knife, which I actually find easier to use for cleanly cutting through tender tomatoes.What kind of bread is best? I love sourdough for the texture and tang, but you can use a multi-grain or seeded whole wheat bread too. I prefer heartier breads to soft ones, so they hold up to toasting.How to pick the best tomatoes? Perfectly ripe tomatoes should be bright in color, shiny, and glossy. They should feel firm when slightly squeezed and smell floral - almost like basil. Weird, right??
