A sweet and tangy cherry tomato jam adds dynamite flavor to this simple panini, pairing beautifully with tender slices of steamed sweet potato, creamy avocado, and crisp, sweet onion. Tomato jam is an American invention, first recorded in the 1940s, known for its balance of acidity, sweetness, and mild spice. This hunger-busting warm sandwich is perfect for special occasions or when you have a bounty of cherry tomatoes to hand. You'll make more cherry tomato jam than you need. It’ll keep for up to two weeks stored in an airtight container in the fridge and is delicious spread on toast, crackers, or other sandwiches.
Tips
How to cook in a skillet: If you don’t have a panini press, weigh the sandwiches down by placing a large skillet on top of them; add a few unopened cans of food to the top skillet. (If you use a heavy cast-iron skillet, you won’t need to add the cans for weight.) Cook over medium-high 2 minutes; turn sandwiches over. Replace skillet and cans; cook 2 minutes more or until sandwiches are golden and heated through.
Gluten-free version: To make this gluten-free, use whole grain, gluten-free bread.
