Roast the peppers yourself. Jarred peppers work in a pinch, but the ones you cook at home until the skin blisters and comes away in clean strips taste completely different. This panini is built around that contrast: soft, sweet peppers against fresh tomato, basil, and a sharp hit of lemon. Assembled right, it eats like summer on bread. Press it hard on the grill so the outside crisps while everything inside softens together.
How to Make Fresh Vegetable Panini
Roasting the peppers
Roast at 350°F for 25 to 30 minutes, then let them cool before peeling. The skin slips off easily once the peppers have steamed inside their own heat. Do not rush this step.
The vegetable marinade
Season the onions and tomatoes with olive oil, lemon juice, oregano, and basil while the peppers roast. A few minutes in that marinade mellows the raw onion and gets everything ready to layer. 
Bread selection
Use a sturdy panini roll or ciabatta that can handle the moisture from the vegetables without falling apart. Softer sandwich bread will not hold up on the grill press.

Frequently Asked Questions
Why do I need to let the vegetable mixture rest for 15 minutes?
Resting lets the lemon juice and olive oil marinate the onions and tomatoes, softening their raw edges and blending the flavors. Skipping this step gives you a less cohesive filling.
Can I use jarred roasted peppers instead of roasting my own?
You can, but drain and pat them dry first. Fresh-roasted peppers have a better texture and more concentrated flavor, so roasting your own is worth the extra time.
Is the mint necessary?
It’s optional but recommended. The mint adds a cool, bright note that pairs well with the basil and lemon. If you skip it, the panini will still taste good but will be less layered.
