Why Choose the Kilner® Food on the Go Jar 1 Litre?
The 1-litre capacity is perfect for single servings of salads, grains, soups, or snacks. Its wide mouth makes filling and cleaning easy, while the secure lid ensures leak-proof transport. The glass construction is non-porous, so it won't absorb odors or stains, and it's safe for use in the microwave (without the lid) and dishwasher.
Compared to plastic containers, glass is more durable and eco-friendly. The Kilner® Food on the Go Jar is also stackable, saving space in your fridge or bag. Its classic design means you can go from fridge to table without transferring food.
- Ideal portion size: 1 litre fits a hearty salad or a generous serving of soup.
- Leak-proof lid: perfect for carrying in a backpack or tote.
- Glass material: keeps food fresh longer and is free from harmful chemicals.
Layered Salads: The Ultimate On-the-Go Lunch
Layered salads are a popular meal prep solution because they stay crisp and fresh. The key is to place heavier, wetter ingredients at the bottom and lighter, drier ones on top. Start with a dressing at the bottom, then add sturdy vegetables like cherry tomatoes, cucumbers, and bell peppers. Next, add protein such as grilled chicken, chickpeas, or hard-boiled eggs. Finally, top with leafy greens and herbs.
When you're ready to eat, simply shake the jar to distribute the dressing, or pour it into a bowl. This method prevents sogginess and keeps your salad fresh for up to three days. The Kilner® Food on the Go Jar's wide mouth makes it easy to add layers and toss the salad right in the jar.
- Dressing at the bottom prevents greens from wilting.
- Use a variety of colors and textures for a nutritious meal.
- Store in the fridge for up to 3 days; shake before eating.
Overnight Oats and Breakfast Parfaits
Mornings are hectic, but with the Kilner® Food on the Go Jar, you can prepare breakfast the night before. Combine rolled oats, milk or yogurt, chia seeds, and your favorite toppings like berries, nuts, or honey. Seal the jar and refrigerate overnight. In the morning, you have a creamy, ready-to-eat breakfast that you can grab on your way out.
You can also create yogurt parfaits with layers of Greek yogurt, granola, and fruit. The glass jar makes your breakfast look appetizing, and the 1-litre size is perfect for a generous serving. Plus, the airtight seal keeps oats fresh and prevents spills.

Soups, Stews, and Sauces to Go
The Kilner® Food on the Go Jar is also great for transporting soups, stews, and sauces. The leak-proof lid ensures no spills in your bag. You can prepare a large batch of soup and portion it into individual jars for easy grab-and-go lunches. The glass material is microwave-safe, so you can heat your soup directly in the jar (remove the lid first).
For sauces and dressings, the 1-litre jar might be larger than needed, but it's perfect for batch cooking. You can store homemade pasta sauce, curry, or chili in the jar and use it throughout the week. The wide mouth makes it easy to pour and clean.
