This is my methods to add some Items to Cart:

 [HttpGet("/UserPanel/AddToCart")]
 public async  Task<IActionResult> ShowCart( )
 {
     await GetTax();

     var cartItems=  _siteService.GetFromSession();
     var cartViewModel = new CartViewModel
     {
         Items = cartItems
     };

     return View(cartViewModel);

 }

 
 public async Task<IActionResult> AddToCart(int chefFoodId)
 {

 
     var item = await _orderService.GetItemByChefFoodId(chefFoodId);
     if (item != null)
     {
           _siteService.SaveInSession(item);
     }

     return RedirectToAction("ShowCart");

 }
     

and this is my method in service:

I have add-to-cart icon on my menu , I want to save chefFoodid first in session , and then if user click on cart in header icon, then goes to AddToCard Method

How can I save ChefFoodId in session before going to addToCard method,without script

should I write new method to save chefFoodid in new session? or have another way?
