If you've been itching to go on a picnic, International Picnic Day celebrated every June 18, is the perfect excuse to go out in the open air and eat delicious food.

Picnics can be traced back to the days after the French Revolution when people could go to the parks again. Today, this simple pastime is enjoyed all over the world. The idea to celebrate this fun and relaxing holiday is to slow down for a bit, go on a picnic with family or a few close friends, relish a succulent meal, and perhaps even play a few games.

If the weather isn't cooperative or there are still some restrictions in your area, you can still enjoy the occasion by having an indoor picnic.

A big part of having a fun picnic is bringing delectable food to share with good company, so let's look at some yummy picnic food ideas to try today. (Courtesy -- Taste of Home, Country Living and Love & Lemons)

BLT Macaroni Salad 

If you love a good BLT sandwich but also want to have macaroni salad during a picnic, then this recipe is for you. It's basically a pasta salad that incorporates the three key ingredients of a BLT: bacon, lettuce and tomato. Combine that with other ingredients such as elbow macaroni, lemon juice and green onions, and you'll have a fresh and delicious take on the BLT.

Skillet Spinach-Artichoke Dip With Fire Roasted Bread

Those who don’t mind doing a bit of cooking while on a picnic may want to try this special recipe. It entails combining decadent ingredients including cream cheese, garlic, sour cream and Parmesan with spinach and artichoke then cooking it in a cast-iron skillet over a grill. Once done, this delicious dip can be slathered over crisp bread that's been drizzled with olive oil and grilled over direct heat.

Tomato, Basil and Artichoke Picnic Sandwich

The name of this recipe alone is already perfect for a picnic. It's quite like a caprese sandwich with edamame spread but no cheese. It also has fresh basil instead of cilantro, so those who aren't quite keen on the latter can certainly enjoy this sandwich. Put together with baby salad greens, this makes for a refreshing sandwich that's perfect for warm weather.

Cracker Jack and Pretzel Treats

Those who can't decide if they'd rather bring a sweet or salty snack for the picnic can bring both using this recipe for snack bars. It combines the flavors of Cracker Jacks, peanuts, salted mini pretzels and salt, and is held together by sweet melted marshmallows and butter. Cut it into bars and you'll have a light, sweet and salty snack that's perfect for the picnic.

Rainbow and Gelatin Cubes

There's always room for dessert and colorful cubes of gelatin are an easy way to add sweetness to your picnic. To make this recipe, one would need to chill each layer of gelatin until set to create a rainbow look. Cut into small squares, and you'll have a satisfying dessert for children and grown-ups alike.
