Chop strawberries into chunks and toss in a saucepan on medium high heat. Cook strawberries, stirring often, until they begin to soften and release water. Turn down to a simmer, add agave, chia seeds, vanilla and salt, and simmer strawberries stirring occasionally until liquid is reduced by half. Remove from heat and let sit for at least 15 minutes to thicken.
To make the toast in photos above, toast two slices of whole wheat bread and lather generously with smooth all-natural peanut butter. Add a heaping spoonful of homemade strawberry jam to each.
