Prep

  1. Onions / Sweet potatoes - If prepping right before cooking, get oven heating / potatoes roasting before continuing with prep. Prep as directed (you can peel the sweet potatoes or leave them unpeeled). Store separately. (Can be done up to 5 days ahead)
  2. Caramelize onions - Heat a frying pan over medium heat. Add cooking oil and then add onions to heated oil. Saute for ~15 minutes, until tender but still crunchy. If it looks like the onions will burn at any point, just add a splash of water. Finish with balsamic vinegar and brown sugar. Cook for another 2 minutes. (Can be done up to 5 days ahead)
  3. Make vinaigrette - (Skip if vinaigrette was made ahead for Tuesday.) Peel and crush garlic. Combine with sun-dried tomatoes, dried basil, balsamic vinegar, red wine vinegar, honey, and olive oil. Blend until smooth with an immersion blender or standing blender. (Can be done up to 5 days ahead)
  4. Peas - If using fresh peas, place in a microwave-safe bowl and cover with a damp paper towel. Cook on high until tender, 2 to 4 minutes. If using frozen peas, defrost.

Make

  1. Heat oven to 400F / 204C. Line a sheet pan with parchment paper.
  2. Brush or toss sweet potato slices with olive oil and some salt. Spread out in a single layer on sheet pan.
  3. Roast potatoes in the oven until tender, turning with a spatula halfway through cooking, 20 to 25 minutes total (the time will vary depending on thickness).
  4. When potatoes are tender, butter one side of each piece of bread with about 1/2 Tbsp (7g) of butter each. Lay out bread buttered-side down. Layer with cheese, onions, sweet potatoes and top with bread, buttered-side up. Continue until all sandwiches are made.
  5. Heat a griddle or a skillet over medium heat. Place sandwiches onto heated surface (as many as can fit) and press down throughout the grilling process with a spatula. Flip once the first side is golden, ~ 3 to 4 minutes.
  6. When sandwiches are nearly finished, toss greens, peas, and almonds together. Add vinaigrette until salad is dressed to your liking. Top with some fresh cracked black pepper.
  7. Serve sandwiches with salad on the side. Enjoy!

my husband and i don't care for the salad, but the grilled cheeses themselves are delish. we have made this one multiple times because of how easy it is (...but we skip the salad).

Delicious! The salad is an excellent, summery alternative to the traditional tomato soup accompaniment, and the flavors of the sweet potatoes, caramelized onions and cheese combined excellent. I did use gruyere instead of fontina because it was what was available :)

Yummy! I should have added a bit more salt to the potatoes, and I'm sad it's not easy to bring leftovers to lunch at work tomorrow, but this was a very solid meal.

Delicious! Husband always complains not enough lamb. Also added sweet peas to the salad. LOVED the sundried tomato dressing. Didn’t love that I had to make two sauces (reduction for lamb was okay but not super exciting and lamb was delicious on its own. Hope to try the grilled sandwiches at some point, but trying to reduce carbs.

very tasty. i used daiya non-dairy cheese shredded very fine on mine, cheddar on theirs. my son thought the onions were too sweet - next time, no sugar. my husband said it's the best sandwich i've ever made.

This was the first real CookSmarts miss for me, which was surprising because each of the ingredients seemed amazing on its own. It just came together really weird. Potatoes on bread just came out super starchy, and the onions overpowered everything. Ate it, but won't be making this one again.
