Grilled Gruyere and Olive Tapenade Sandwich
Remove 4 sun-dried tomatoes and 2 Tbs oil from jar (put the rest away). Set 1 Tbs oil aside. Combine tomatoes, 1 Tbs oil, olives, and garlic in a mini food processor; process until mostly smooth, scraping sides of bowl once.
Brush one side of each bread slice with remaining 1 Tbs olive oil. Spread 1.5 Tbs olive mixture on each of 4 bread slices, oil side down. Top each bread slice with 1 Tbs cheese, 2 tomato slices, and cheese. Top with remaining bread.
Heat skillet over medium-high heat and toast until cheese melts.
