Prep the bread. Slice the ciabatta or boule horizontally. If the crumb is very fluffy, gently pull out a little from the top half to make space for the fillings. Brush the cut sides with a thin layer of olive oil.

Make the spread. In a small bowl, mix the mayo, Dijon, grated garlic, and a squeeze of lemon. Add a pinch of salt and pepper. Taste and adjust—this should be bright and savory, not heavy.

Season the tomatoes. Slice the tomatoes into medium rounds. Lay them on a plate and sprinkle with salt and pepper. This step wakes up the flavor and helps them release excess juice.

Drain the artichokes. Pat them dry with a paper towel to avoid sogginess. If they’re in large pieces, halve or quarter them for easier layering.

Spread and layer. Spread the garlicky mayo on both cut sides of the bread. On the bottom half, add a layer of cheese (if using) to create a moisture barrier. Then add the tomatoes, artichokes, and basil leaves.

Add greens (optional). A small handful of arugula or spinach adds a peppery note and some crunch. Keep it light so the sandwich closes neatly.

Season smartly. Add a sprinkle of black pepper and a pinch of red pepper flakes if you like heat. Drizzle a tiny bit more olive oil over the tomatoes for richness.

Close and press. Place the top half on and press gently with your hands. If you have time, wrap the whole sandwich tightly in parchment or plastic wrap and place a baking sheet with a few cans on top for 15–20 minutes. This helps it set and makes clean slices.

Slice for sharing. Use a serrated knife to cut into halves, then into smaller wedges. Wipe the knife between cuts for neat edges.

Pack it up. Rewrap and store in a cooler or insulated bag until you’re ready to eat. Bring napkins—the tomatoes are juicy in the best way.
